description: We study time-inconsistent recursive stochastic control problems, i.e., for which the Bellman principle of optimality does not hold. For this class of problems classical optimal controls may fail to exist, or to be relevant in practice, and dynamic programming is not easily applicable. Therefore, the notion of optimality is defined through a game-theoretic framework by means of subgame perfect equilibrium: we interpret our preference changes which, realistically, are inconsistent over time, as players in a game for which we want to find a Nash equilibrium. The approach followed in our work relies on the stochastic (Pontryagin) maximum principle: we adapt the classical spike variation technique to obtain a characterisation of equilibrium strategies in terms of a generalised second-order Hamiltonian function defined through pairs of backward stochastic differential equations, even in the multidimensional case. The theoretical results are applied in the financial field to finite horizon investment-consumption policies with non-exponential actualisation. Here the existence of non-trivial equilibrium policies is also ascertained.

description: Starting from general expressions of well-chosen symmetric nuclear matter quantities derived for both zero- and finite-range effective theories, we derive the contributions to the effective mass. We first show that, independently of the range, the two-body contribution is enough to describe correctly the saturation mechanism but gives an effective mass value around $m^*/m \simeq 0.4$. Then, we show that the full interaction (by instance, an effective two-body density-dependent term on top of the pure two-body term) is needed to reach the accepted value $m^*/m \simeq 0.7-0.8$.

description: We study a general corresponding principle between discrete-variable quantum states and continuous-variable (especially, restricted on Gaussian) states via quantum purification method. In the previous work, we have already investigated an information-theoretic correspondence between the Gaussian maximally mixed states (GMMSs) and their purifications known as Gaussian maximally entangled states (GMESs) in [Phys. Lett. A {\bf 380}, 3607 (2016)]. We here compare an $N\times N$-dimensional maximally entangled state to the GMES we proposed previously, through an explicit calculation of quantum fidelity between those entangled states. By exploiting the results, we naturally conclude that our GMES is more suitable to the concept of \emph{maximally entangled} state in Gaussian quantum information, and thus it might be useful or applicable for quantum information tasks than the two-mode squeezed vacuum (TMSV) state in the Gaussian regime.

Sin embargo, estas dos conclusiones resultarían no solo apresuradas, sino equivocadas

description: Many algorithms and applications involve repeatedly solving variations of the same inference problem, for example to introduce new evidence to the model or to change conditional dependencies. As the model is updated, the goal ofadaptive inference is to take advantage of previously computed quantities to perform inference more rapidly than from scratch. In this paper, we present algorithms for adaptive exact inference on general graphs that can be used to efficiently compute marginals and update MAP configurations under arbitrary changes to the input factor graph and its associated elimination tree. After a linear time preprocessing step, our approach enables updates to the model and the computation of any marginal in time that is logarithmic in the size of the input model. Moreover, in contrast to max-product our approach can also be used to update MAP configurations in time that is roughly proportional to the number of updated entries, rather than the size of the input model. To evaluate the practical effectiveness of our algorithms, we implement and test them using synthetic data as well as for two real-world computational biology applications. Our experiments show that adaptive inference can achieve substantial speedups over performing complete inference as the model undergoes small changes over time.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: We introduce a new approach to Monge-Ampere geometry based on techniques from higher symplectic geometry. Our work is motivated by the application of Monge-Ampere geometry to the Poisson equation for the pressure that arises for incompressible Navier-Stokes flows. Whilst this equation constitutes an elliptic problem for the pressure, it can also be viewed as a non-linear partial differential equation connecting the pressure, the vorticity, and the rate-of-strain. As such, it is a key diagnostic relation in the quest to understand the formation of vortices in turbulent flows. We study this equation via an associated (higher) Lagrangian submanifold in the cotangent bundle to the configuration space of the fluid. Using our definition of a (higher) Monge-Ampere structure, we study an associated metric on the cotangent bundle together with its pull-back to the (higher) Lagrangian submanifold. The signatures of these metrics are dictated by the relationship between vorticity and rate-of-strain, and their scalar curvatures can be interpreted in a physical context in terms of the accumulation of vorticity, strain, and their gradients. We show explicity, in the case of two-dimensional flows, how topological information can be derived from the Monge-Ampere geometry of the Lagrangian submanifold. We also demonstrate how certain solutions to the three-dimensional incompressible Navier-Stokes equations, such as Hill's spherical vortex and an integrable case of Arnol'd-Beltrami-Childress flow, have symmetries that facilitate a formulation of these solutions from the perspective of (higher) symplectic reduction.

description: Car safety measures can be most effective when the cars on a street coordinate their control actions using distributed cooperative control. While each car optimizes its navigation planning locally to ensure the driver reaches his destination, all cars coordinate their actions in a distributed way in order to minimize the risk of safety hazards and collisions. These systems control the physical aspects of car movement using cyber technologies like local and remote sensor data and distributed V2V and V2I communication. They are thus cyber-physical systems. In this paper, we consider a distributed car control system that is inspired by the ambitions of the California PATH project, the CICAS system, SAFESPOT and PReVENT initiatives. We develop a formal model of a distributed car control system in which every car is controlled by adaptive cruise control. One of the major technical difficulties is that faithful models of distributed car control have both distributed systems and hybrid systems dynamics. They form distributed hybrid systems, which makes them very challenging for verification. In a formal proof system, we verify that the control model satisfies its main safety objective and guarantees collision freedom for arbitrarily many cars driving on a street, even if new cars enter the lane from on-ramps or multi-lane streets. The system we present is in many ways one of the most complicated cyber-physical systems that has ever been fully verified formally.

description: La infraestructura es un elemento prioritario en los sistemas económicos y territorial de los países. Es esencial para mejorar la calidad de vida de sus habitantes y la inclusión social, así mismo, mejora su ventaja competitiva. En este sentido, es un elemento vertebrador de la estructura económica de los países y de sus mercados (CEPAL, 2004; BID, 2014). Colombia, como lo mencionan varios estudios, requiere grandes inversiones en materia de infraestructura que permita el crecimiento de la industria, sin embargo, la demanda de los cada vez más escasos recursos públicos obliga a buscar estrategias que permitan una mayor vinculación del sector privado. En los últimos años, los flujos de inversión privada se han venido desarrollando. Es partir de la década de 1990, y en línea con la tendencia mundial, que Colombia hizo la transición a un entorno de estrecha cooperación entre los sectores público y privado. Los flujos de inversión privada han generado un crecimiento no sólo de carácter económico, sino en lo que respecta a las relaciones internacionales con el fortalecimiento de los tratados comerciales, y el intercambio de innovación en tecnología, procesos y conocimientos. De este modo, ha permitido que la economía tenga un desarrollo progresivo, lo que refleja que la inversión privada puede tener efectos positivos en el PIB del país.
description: Infrastructure is a priority element in the economic and territorial systems of countries. It is essential to improve the quality of life of its inhabitants and social inclusion, as well as improving its competitive advantage. In this sense, it is a backbone element of the economic structure of countries and their markets (CEPAL, 2004; IDB, 2014). As several studies mention, Colombia requires significant investments in infrastructure to allow the growth of the industry. However, the demand for increasingly scarce public resources obliges us to seek strategies that allow for greater private sector involvement. In recent years, private investment flows have been developing. It is since the 1990s, and in line with the global trend, that Colombia made the transition to an environment of close cooperation between the public and private sectors. Private investment flows have generated growth not only of an economic nature but also regarding international relations, with the strengthening of commercial treaties and the exchange of innovation in technology, processes, and knowledge. In this way, it has allowed the economy to have progressive development, which reflects that private investment can have positive effects on the country's GDP.

description: Many data mining applications can benefit from adapt- ing existing classifiers to new data with shifted distribu- tions. In this paper, we present Adaptive Support Vector Machine (Adapt-SVM) as an efficient model for adapting a SVM classifier trained from one dataset to a new dataset where only limited labeled examples are available. By in- troducing a new regularizer into SVM's objective function, Adapt-SVM aims to minimize both the classification error over the training examples, and the discrepancy between the adapted and original classifier. We also propose a selective sampling strategy based on the loss minimization principle to seed the most informative examples for classifier adap- tation. Experiments on an artificial classification task and on a benchmark video classification task shows that Adapt- SVM outperforms several baseline methods in terms of ac- curacy and/or efficiency.
Geometric phases, Everett's many-worlds interpretation of quantum mechanics, and wormholes

description: We present how the formalism of geometric phases in adiabatic quantum dynamics provides geometric realisations permitting to ``embody'' the Everett's many-worlds interpretation of quantum mechanics, including interferences between the worlds needed for the probability changes and the decoherence processes needed to solve the preferred basis problem. We show also that this geometric realisation is intimately related to quantum gravity (especially to matrix models), showing that the many-world interpretation can be consistent with quantum gravity. The concept of wormhole borrowed to general relativity is central in this geometric realisation. It appears not only as an image by analogy to help the interpretations, but also as a true physical model of quantum wormhole in quantum gravity, the two ones being consistent which each other.

description: This work is part of a series of studies focusing on the environment and the properties of the X-ray selected active galactic nuclei (AGN) population from the XXL survey. The present survey, given its large area, continuity, extensive multiwavelength coverage, and large-scale structure information, is ideal for this kind of study. Here, we focus on the XXL-South (XXL-S) field. Our main aim is to study the environment of the various types of X-ray selected AGN and investigate its possible role in AGN triggering and evolution. We studied the large-scale (>1 Mpc) environment up to redshift z=1 using the nearest neighbour distance method to compare various pairs of AGN types. We also investigated the small-scale environment (<0.4 Mpc) by calculating the local overdensities of optical galaxies. In addition, we built a catalogue of AGN concentrations with two or more members using the hierarchical clustering method and we correlated them with the X-ray galaxy clusters detected in the XXL survey. It is found that radio detected X-ray sources are more obscured than non-radio ones, though not all radio sources are obscured AGN. We did not find any significant differences in the large-scale clustering between luminous and faint X-ray AGN, or between obscured and unobscured ones, or between radio and non-radio sources. At local scales (<0.4 Mpc), AGN typically reside in overdense regions, compared to non-AGN; however, no differences were found between the various types of AGN. A majority of AGN concentrations with two or more members are found in the neighbourhood of X-ray galaxy clusters within <25-45 Mpc. Our results suggest that X-ray AGN are typically located in supercluster filaments, but they are also found in over- and underdense regions.

description: In a previous report (Raju et al.,2023) we concluded that, if the goal was to preserve events such as saccades, microsaccades, and smooth pursuit in eye-tracking recordings, data with sine wave frequencies less than 100 Hz (-3db) were the signal and data above 100 Hz were noise. We compare 5 filters in their ability to preserve signal and remove noise. Specifically, we compared the proprietary STD and EXTRA heuristic filters provided by our EyeLink 1000 (SR-Research, Ottawa, Canada), a Savitzky-Golay (SG) filter, an infinite impulse response (IIR) filter (low-pass Butterworth), and a finite impulse filter (FIR). For each of the non-heuristic filters, we systematically searched for optimal parameters. Both the IIR and the FIR filters were zero-phase filters. Mean frequency response profiles and amplitude spectra for all 5 filters are provided. In addition, we examined the effect of our filters on a noisy recording. Our FIR filter had the sharpest roll-off of any filter. Therefore, it maintained the signal and removed noise more effectively than any other filter. On this basis, we recommend the use of our FIR filter. Several reports have shown that filtering increased the temporal autocorrelation of a signal. To address this, the present filters were also evaluated in terms of autocorrelation (specifically the first 3 lags). Of all our filters, the STD filter introduced the least amount of autocorrelation.

Dado que el objetivo del estudio será la posible fluctuación del elemento subjetivo del tipo penal para el delito de Genocidio y su posibilidad de ampliar el espectro de imputación de quienes cometen el injusto, el diseño de la investigación se enmarca en una metodología no experimental, dado que el tema de investigación alterna tanto el espectro fáctico vigente y el trasegar histórico, igualmente se hace necesario que este enfoque no experimental sea de carácter longitudinal o evolutivo, es decir que los datos puestos de manifiesto en la tesis están basados en los cambios jurídicos que el tipo de Genocidio ha obtenido desde sus inicios hasta este momento.
description: The approach of this thesis has as its main interest the crime of Genocide with respect to the dogmatic scheme of the crime, especially the subjective element of the criminal type. It is indicated that the investigation covers both the definition set forth in article 101 of Law 599 of 2000 of the Colombian Penal Code, as well as in article 6 of the Rome Statute of the International Criminal Court. Given that the objective of the study will be the possible fluctuation of the subjective element of the criminal type for the crime of Genocide and its possibility of expanding the spectrum of imputation of those who commit the injustice, the design of the investigation is part of a non-experimental methodology, given that the research topic alternates both the current factual spectrum and the historical transfer, it is also necessary that this nonexperimental approach be of a longitudinal or evolutionary nature, that is to say that the data revealed in the thesis are based on the legal changes that the type of Genocide has obtained since its inception until now.

description: TOI-561 is a galactic thick disk star hosting an ultra-short period planet of 1.45 R⊕: one of the oldest known Earth-sized exoplanets (∼10 Gyr), and among the first discovered beyond the thin disk of our galaxy. As a thick disk star, TOI-561 is one of the most iron depleted (-0.41 dex) and alpha-enriched (0.23 dex) exoplanet hosts. To determine the composition of this planet, we collected high-precision Radial Velocity measurements and used equation-of-state modeling for iron and silicate rock. We have determined that the low density of TOI-561 b requires this planet to have a volatile envelope, despite its size and proximity to its host star.

description: Biomimetic scale-covered substrates are architected meta-structures exhibiting fascinating emergent nonlinearities via the geometry of collective scales contacts. In spite of much progress in understanding their elastic nonlinearity, their dissipative behavior arising from scales sliding is relatively uninvestigated in the dynamic regime. Recently discovered is the phenomena of viscous emergence, where dry Coulomb friction between scales can lead to apparent viscous damping behavior of the overall multi-material substrate. In contrast to this structural dissipation, material dissipation common in many polymers has never been considered, especially synergestically with geometrical factors. This is addressed here for the first time, where material visco-elasticity is introduced via a simple Kelvin-Voigt model for brevity and clarity. The results contrast the two damping sources in these architectured systems: material viscoelasticity, and geometrical frictional scales contact. It is discovered that although topically similar in effective damping, viscoelsatic damping follows a different damping envelope than dry friction, including starkly different effects on damping symmetry and specific damping capacity.

Renormalized Kalb-Ramond model: duality and generalized potential

Subjects: subject: High Energy Physics - Theory (hep-th)

description: Considering the recent advances, the weak correlation between the massive Kalb-Ramond and the Proca interacting models is investigated by means of a set of complementary quantum field techniques beyond the semi-classical approach. A consistent framework to discuss the abrupt degree of freedom variation in the massless limit is established. In this manner, the Stueckelberg procedure is generalized for the present case to derive Ward-Takahashi constraints. By adding couplings with fermionic matter fields, even the weak dual correlation is broken due to the explicit form of the radiative corrections. However, considering the master action approach, the fermionic 1(PI) functions of the Proca electrodynamics are reproduced in all orders of perturbation. A well-defined procedure to eliminate non-desirable modes emerging from quantum corrections is successfully applied for this model. Last, but not least, we prove that this structure can also provide a spin interaction which is relevant even at macroscopic distances, being a completion for a recently proposed confining potential. This is based on an interacting theory in compliance with renormalizability.

description: We present novel asymptotically global AdS$_4$ solutions, constructed by turning on a dipolar differential rotation at the conformal boundary. At fixed energy and boundary profile, we find two different geometries: a horizonless spacetime, and a deformed, hourglass shaped black hole with zero net angular momentum. Both solutions exist up to some maximum amplitudes of the boundary profile, and develop an ergoregion attached to the boundary before the maximum amplitude is reached. We show that both spacetimes develop hair as soon as the ergoregion develops. Furthermore, we discuss the full phase diagram, including the possibility of phases with disconnected horizons, by considering the Mathisson-Papapetrou equations for a spinning test particle. Finally, we provide a first principle derivation of the superradiant bound purely from CFT data, and outline possible scenarios for the late time evolution of the system.

description: La ejecución de los recursos provenientes del Sistema General de Regalías está condicionado a la formulación de proyectos bajo la Metodología General Ajustada (MGA), siendo esta una herramienta metódica para facilitar el proceso de conceptualización, diseño, ejecución y evaluación de proyectos inversión pública en los territorios. La MGA no asegura el éxito del proyecto lo que significa que la calidad de la formulación no se centra en el uso de la herramienta sino en la confiabilidad de la información que se registre en ella. Por lo tanto, un primer obstáculo de los entes territoriales al momento de ejecutar recursos del SGR es la formulación técnica del proyecto. Para ello es primordial que el formulador conozca técnicamente cómo se estructura un proyecto de inversión. Otro obstáculo es la carencia de talento humano capacitado puesto que no en todos los entes territoriales los funcionarios al frente de los Bancos de Proyectos Municipales ostentan un perfil técnico afín con una gerencia de proyectos, situación que es más evidente en los municipios de sexta y quinta categoría. Por tanto, uno de los mayores retos de las entidades territoriales es el fortalecimiento de sus Bancos de Proyectos Municipales
description: The execution of the resources coming from the General System of Royalties is conditioned to the formulation of projects under the General Adjusted Methodology (MGA), being this a methodical tool to facilitate the process of conceptualization, design, execution and evaluation of public investment projects in the territories. The MGA does not ensure the success of the project, which means that the quality of the formulation does not focus on the use of the tool, but rather on the reliability of the information recorded in it. Therefore, a first obstacle for territorial entities when executing SGR resources is the technical formulation of the project. For this, it is essential that the formulator know technically how an investment project is structured. Another obstacle is the lack of trained human talent since not in all territorial entities the officials in charge of the Municipal Project Banks have a technical profile related to project management, a situation that is more evident in the sixth and fifth municipalities. category. Therefore, one of the greatest challenges for territorial entities is the strengthening of their Municipal Project Banks.

description: The transfer functions of sensory neurons are known to adapt to the statistics of the input signals. It is however unclear whether such adaptation arises from the nonlinear dynamics of the neuron or emerges from the collective interaction among neurons embedded in a network. We investigated the Hodgkin–Huxley (HH) neuronal model's response to Gaussian white noise signals of different variances and found that the recovered kernel adapt its preferred temporal frequency and its energy gains according to noise variance. This adaptation is likely a consequence of the cooperative interaction between the noises and the bifurcation dynamics of the neurons.

The research focused on five critical HR areas: recruitment efficiency,employee engagement, performance management, training effectiveness, and HR datamanagement. Using a mixed-methods approach combining surveys, interviews, and actionresearch, the study implemented and evaluated targeted improvements over a 12-week period.Key findings revealed that social media and referral-based recruitment strategies reduced timeto-hire by 20%, while quarterly performance reviews increased employee satisfaction scoresby 21%. Structured onboarding programs improved new hire retention by 17%, and data-driventraining initiatives boosted productivity by 22%. Additionally, the implementation of an HRInformation System (HRIS) reduced administrative workload by 33%, demonstrating the valueof digitizing HR processes.The study's outcomes validate that evidence-based HR strategies can significantly enhanceorganizational efficiency and employee satisfaction in the IT sector. By aligning HR practiceswith business objectives, IT Company achieved measurable improvements in talentacquisition, workforce motivation, and operational productivity. These findings provide areplicable framework for similar organizations facing HR-related challenges in competitive,technology-driven environments.

description: Se investigó desde el paradigma post positivista, con un enfoque transaccional descriptivo, donde se correlacionaron las categorías calidad de vida laboral y bienestar psicológico. Una muestra de 247 conductores de SITP de la empresa SUMA S.A.S, diligenciaron la escala de Bienestar Psicológico de Ryff (1989) en su versión abreviada y la escala de calidad de vida laboral de Córdoba y Moreno (2013), a partir de estos resultados cuantitativos se realizaron dos espacios de grupo focal para profundizar en las narrativas alrededor de los datos. Esta investigación de corte mixto encontró entre sus resultados el impacto de la calidad de vida laboral sobre el bienestar psicológico de los trabajadores, encontrando aspectos fundamentales para pensarse este problema como lo son la extensión e intensidad de jornada laboral, asalario, multas, sanciones económicas, seguridad, exposición a estrés, reconocimiento dentro de la empresa, entre otros.
description: It has been discovered that maintain the psychological well-being of public transport drivers is related with a lower rate of accidents or dangerous driving. Unfortunately, for the SITP transport system there are no current data on the relationship between quality of working life and psychological well-being of the operators. The present investigation was approached from the post-positivist paradigm, with a descriptive transactional method. The sample consisted of 247 drivers from the public transport system SITP of the company SUMA S.A.S, they completed the shortened version of the Ryff’s Psychological Well- Being Scale (1989), and the Scale of quality of working life by Córdoba & Moreno (2013). Based on these quantitative results, two focus groups were held, in order, to deepen the narratives around the data. This investigation of mixed nature, found among its results a correlation between the impact of quality of working life with psychological well-being of the workers. This research corroborates the relationship that exist between psychological well-being and quality of working life, finding problematic sources of this distress such as the working hours, exposure to stress and problems related with the safety of the operators.

description: An overview about C*-algebra bundles with a Z-grading is presented, with particular emphasis on classification questions. In particular, we discuss the role of the representable KK(X ; -, -)-bifunctor introduced by Kasparov. As an application, we consider Cuntz-Pimsner algebras associated with vector bundles, and give a classification in terms of K-theoretical invariants in the case in which the base space is an n-sphere.

Leptoquarks in Flavour Physics

description: While the LHC has not directly observed any new particle so far, experimental results from LHCb, BELLE and BABAR point towards the violation of lepton flavour universality in $b\to s\ell^{+}\ell^{-}$ and $b\to c\ellν$. In this context, also the discrepancy in the anomalous magnetic moment of the muon can be interpreted as a sign of lepton flavour universality violation. Here we discuss how these hints for new physics can also be explained by introducing leptoquarks as an extension of the Standard Model. Indeed, leptoquarks are good candidates to explain the anomaly in the anomalous magnetic moment of the muon because of an $m_{t}/m_μ$ enhanced contribution giving correlated effects in $Z$ boson decays which is particularly interesting in the light of future precision experiments.

description: Automatic Speech Recognition (ASR) in medical contexts has the potential to save time, cut costs, increase report accuracy, and reduce physician burnout. However, the healthcare industry has been slower to adopt this technology, in part due to the importance of avoiding medically-relevant transcription mistakes. In this work, we present the Clinical BERTScore (CBERTScore), an ASR metric that penalizes clinically-relevant mistakes more than others. We demonstrate that this metric more closely aligns with clinician preferences on medical sentences as compared to other metrics (WER, BLUE, METEOR, etc), sometimes by wide margins. We collect a benchmark of 18 clinician preferences on 149 realistic medical sentences called the Clinician Transcript Preference benchmark (CTP) and make it publicly available for the community to further develop clinically-aware ASR metrics. To our knowledge, this is the first public dataset of its kind. We demonstrate that CBERTScore more closely matches what clinicians prefer.

description: The linearized Boltzmann collision operator has a central role in many important applications of the Boltzmann equation. Recently some important classical properties of the linearized collision operator for monatomic single species were extended to multicomponent monatomic gases and polyatomic single species. For multicomponent polyatomic gases, the case where the polyatomicity is modelled by a discrete internal energy variable was considered lately. Here we considers the corresponding case for a continuous internal energy variable. Compactness results, saying that the linearized operator can be decomposed into a sum of a positive multiplication operator, the collision frequency, and a compact operator, bringing e.g., self-adjointness, is extended from the classical result for monatomic single species, under reasonable assumptions on the collision kernel. With a probabilistic formulation of the collision operator as a starting point, the compactness property is shown by a decomposition, such that the terms are, or at least are uniform limits of, Hilbert-Schmidt integral operators and therefore are compact operators. Moreover, bounds on - including coercivity of - the collision frequency are obtained for a hard sphere like, as well as hard potentials with cutoff like, models, from which Fredholmness of the linearized collision operator follows, as well as its domain.
