description: Abstract – This paper presents the point of view of school principals and teachers, who participate in training activities on school evaluation and self-evaluation. The development of evaluation capacity building is a crucial issue in the debate on the implementation of the Italian Evaluation System. National and international studies point out the relevance to take a decentralized perspective in supporting of schools’ self-assessment processes. The perspective of the participants in this training activity takes into account the characteristics of the courses, the expectations and needs, the opportunities for an open dialogue, mutual exchange and comparison, the evaluation skills learned and the repercussions in school contexts. Riassunto – Questo contributo presenta il punto di vista di dirigenti scolastici e docenti partecipanti ad alcuni percorsi formativi sui temi della valutazione e autovalutazione delle scuole, finalizzati a rafforzare le competenze professionali del personale scolastico. Il tema dello sviluppo delle capacità per la valutazione delle scuole è infatti centrale nel dibattito sull’implementazione del Sistema Nazionale di Valutazione. Le ricerche nazionali e internazionali richiamano la necessità di assumere una prospettiva decentrata nel sostegno alle scuole, finanche nelle iniziative a supporto dei processi di autovalutazione. Si presenta il punto di vista dei partecipanti alle attività formative in merito a bisogni e aspettative, caratteristiche dei corsi, opportunità di scambio e di confronto, competenze valutative apprese e ricadute nei contesti scolastici. Keywords – self-evaluation, training, evaluation skills, collaborative learning, peer review Parole chiave – autovalutazione, formazione, competenze valutative, apprendimento collaborativo, revisione tra pari

description: In this paper we investigate pattern formation in Keller--Segel chemotaxis models over a multi--dimensional bounded domain subject to homogeneous Neumann boundary conditions. It is shown that the positive homogeneous steady state loses its stability as chemoattraction rate $χ$ increases. Then using Crandall--Rabinowitz local theory with $χ$ being the bifurcation parameter, we obtain the existence of nonhomogeneous steady states of the system which bifurcate from this homogeneous steady state. Stability of the bifurcating solutions is also established through rigorous and detailed calculations. Our results provide a selection mechanism of stable wavemode which states that the only stable bifurcation branch must have a wavemode number that minimizes the bifurcation value. Finally we perform extensive numerical simulations on the formation of stable steady states with striking structures such as boundary spikes, interior spikes, stripes, etc. These nontrivial patterns can model cellular aggregation that develop through chemotactic movements in biological systems.

description: Absolute space is eliminated from the body of mechanics by gauging translations and rotations in the Lagrangian of a classical system. The procedure implies the addition of compensating terms to the kinetic energy, in such a way that the resulting equations of motion are valid in any frame. The compensating terms provide inertial forces depending on the total momentum P, intrinsic angular momentum J and intrinsic inertia tensor I. Therefore, the privileged frames where Newton's equations are valid (Newtonian frames) are completely determined by the matter distribution of the universe (Machianization). At the Hamiltonian level, the gauge invariance leads to first class constraints that remove those degrees of freedom that make no sense once the absolute space has been eliminated. This reformulation of classical mechanics is entirely relational, since it is a dynamics for the distances between particles. It is also Machian, since the rotation of the rest of the universe produces centrifugal effects. It then provides a new perspective to consider the foundational ideas of general relativity, like Mach's principle and the weak equivalence principle. With regard to the concept of time, the absence of an absolute time is known to be a characteristic of parametrized systems. Furthermore, the scale invariance of those parametrized systems whose potentials are inversely proportional to the squared distances can be also gauged by introducing another compensating term associated with the intrinsic virial G (shape-dynamics).

description: We investigate the admissible vector-valued modular forms having three independent characters and vanishing Wronskian index and determine which ones correspond to genuine 2d conformal field theories. This is done by finding bilinear coset-type relations that pair them into meromorphic characters with central charges 8, 16, 24, 32 and 40. Such pairings allow us to identify some characters with definite CFTs and rule out others. As a key result we classify all unitary three-character CFT with vanishing Wronskian index, excluding $c=8,16$. The complete list has two infinite affine series $B_{r,1},D_{r,1}$ and 45 additional theories. As a by-product, at higher values of the total central charge we also find constraints on the existence or otherwise of meromorphic theories. We separately list several cases that potentially correspond to Intermediate Vertex Operator Algebras.

description: We study the effects of non-standard interactions on the oscillation pattern of atmospheric neutrinos. We use neutrino oscillograms as our main tool to infer the role of non-standard interactions (NSI) parameters at the probability level in the energy range, $E \in [1,20]$ GeV and zenith angle range, $\cos θ\in [-1,0]$. We compute the event rates for atmospheric neutrino events in presence of NSI parameters in the energy range $E \in [1,10]$ GeV for two different detector configurations - a magnetized iron calorimeter and an unmagnetized liquid Argon time projection chamber which have different sensitivities to NSI parameters due to their complementary characteristics. As an application, we discuss how NSI parameter, $ε_{μτ}$ impacts the determination of the correct octant of $θ_{23}$.

Multipartite Rational Functions

description: Consider a tensor product of free algebras over a field $\mathbbm k$, the so-called multipartite free algebra $\mathcal{A}=\mathbbm k \Langle X^{(1)} \Rangle \otimes\cdots\otimes\mathbbm k \Langle X^{(G)} \Rangle$. It is well-known that $\mathcal{A}$ is a domain, but not a fir nor even a Sylvester domain. Inspired by recent advances in free analysis, formal rational expressions over $\mathcal{A}$ together with their matrix representations in $\operatorname{Mat}_{n_1}\otimes\cdots\otimes\operatorname{Mat}_{n_G}$ are employed to construct a skew field of fractions $\mathcal{U}$ of $\mathcal{A}$, whose elements are called multipartite rational functions. It is shown that $\mathcal{U}$ is the universal skew field of fractions of $\mathcal{A}$ in the sense of Cohn. As a consequence a multipartite analog of Amitsur's theorem on rational identities relating evaluations in matrices over $\mathbbm k$ to evaluations in skew fields is obtained. The characterization of $\mathcal{U}$ in terms of matrix evaluations fits naturally into the wider context of free noncommutative function theory, where multipartite rational functions are interpreted as higher order noncommutative rational functions with an associated difference-differential calculus and linear realization theory. Along the way an explicit construction of the universal skew field of fractions of $D\otimes \mathbbm k \Langle X \Rangle$ for an arbitrary skew field $D$ is given using matrix evaluations and formal rational expressions.

description: Let $V$ be a complete discrete valuation ring with fraction field $F$ of characteristic zero and with residue field \mathbb F. We introduce analytic cyclic homology of complete torsion-free bornological algebras over $V$. We prove that it is homotopy invariant, stable, invariant under certain nilpotent extensions, and satisfies excision. We use these properties to compute it for tensor products with dagger completions of Leavitt path algebras. If $R$ is a smooth commutative $V$-algebra of relative dimension $1$, then we identify the analytic cyclic homology of its dagger completion with Berthelot's rigid cohomology of $R\otimes_V\mathbb F$.

description: Terrorist attacks not only harm citizens but also shift their attention, which has long-lasting impacts on public opinion and government policies. Yet measuring the changes in public attention beyond media coverage has been methodologically challenging. Here we approach this problem by starting from Wikipedia's répertoire of 5.8 million articles and a sample of 15 recent terrorist attacks. We deploy a complex exclusion procedure to identify topics and themes that consistently received a significant increase in attention due to these incidents. Examining their contents reveals a clear picture: terrorist attacks foster establishing a sharp boundary between "Us" (the target society) and "Them" (the terrorist as the enemy). In the midst of this, one seeks to construct identities of both sides. This triggers curiosity to learn more about "Them" and soul-search for a clearer understanding of "Us". This systematic analysis of public reactions to disruptive events could help mitigate their societal consequences.

description: The understanding of the origin of $1/f$ magnetic flux noise commonly observed in superconducting devices such as SQUIDS and qubits is still a major unsolved puzzle. Here we discuss the possibility that a significant part of the observed low-frequency flux noise measured in these devices is ultimately seeded by cosmological fluctuations. We consider a theory where a primordial flux noise field left over in unchanged form from an early inflationary or quantum gravity epoch of the universe intrinsically influences the phase difference in SQUIDs and qubits. The perturbation seeds generated by this field can explain in a quantitatively correct way the form and amplitude of measured low-frequency flux noise spectra in SQUID devices if one takes as a source of fluctuations the primordial power spectrum of curvature fluctuations as measured by the Planck collaboration. Our model predicts flux noise with a spectrum given by an $1/f^{2-n_s}$ spectrum, where $n_s=0.96$ is the spectral index of the near-scale invariant primordial density fluctuations. For the typical amplitude of this cosmologically generated universal flux noise we theoretically calculate the average value $δΦ/Φ_0 =3.41 \cdot 10^{-6}$ at 1Hz. These theoretical predictions are in excellent agreement with recent low-frequency flux noise measurements of various experimental groups. Magnetic flux noise, so far mainly considered as a nuisance for electronic devices, may thus contain valuable information about fluctuation spectra in the very early universe.

Creators: name: Versace, Alessandro
Publisher: name: Università degli Studi di Ferrara

description: Abstract – A lesson is not a time marked by the hands of a clock, a Kronos, it is rather a subjective time within which it goes beyond the hypercognitivist pedagogical model and/or that of a school as a "temple of culture”, where the corrective-repressive system denied culture as the “humanization of life”. Every single gesture that manages to move the desire for knowledge in the student, should not be ascribed only to the motivational dimension, which could also be useful for understanding the reason for a certain action, but also to the emotional one, since there can be no teaching without effects education, just as there cannot be a training without the effects of education transmission. The teacher must produce emptiness and therefore eliminate any stereotype to make room for the new, the unexpected, for that emotional intuition that allows you to grasp the meaning both for a higher emotional intelligence, and to go beyond those now consolidated forms of empathic theatricality. Riassunto – La lezione non è un tempo scandito dalle lancette di un orologio, un Kronos, è piuttosto un tempo soggettivo all’interno del quale si oltrepassa il modello pedagogico ipercognitivista e/o quello di una scuola come “tempio della cultura”, dove il sistema correttivo-repressivo negava la cultura come “umanizzazione della vita”. Ogni singolo gesto che riesce a muovere il desiderio di conoscenza nell’allievo, non va ascritto solo alla dimensione motivazionale, che potrebbe anche essere utile a comprendere il perché di una certa azione, ma anche a quella emozionale, poiché non può esserci insegnamento senza effetti educativi, così come non può esistere una formazione priva di effetti di trasmissione dell’istruzione. L’insegnante deve produrre il vuoto e dunque eliminare ogni stereotipo per fare spazio al nuovo, all’inatteso, a quell’intuizione emozionale che consente di cogliere il senso sia per una più alta intelligenza emotiva, sia per andare oltre quelle forme ormai consolidate di teatralità empatica. Keywords – emotions, feelings, school, education, pedagogy Parole chiave – emozioni, sentimenti, scuola, educazione, pedagogia

description: Biotherapeutic development presents a myriad of challenges in relation to delivery, in particular for protein therapeutics. Protein delivery is complicated due to hydrophilicity, size, rate of degradation in vivo, low permeation through biological barriers, pH and temperature sensitivity, as well as the need to conserve its quaternary structure to retain function. To preserve therapeutic levels in vivo, proteins require frequent administration due to their short half-lives. Formulation strategies combining proteins with lipid carriers for parenteral administration show potential for improving bioavailability, while preserving protein activity and bypassing the mucosal barriers of the body. Encapsulating protein in long acting injectable delivery systems can improve therapeutic indices by prolonging and controlling protein release and reducing the need for repeat interventions. Two lyotropic crystal forming lipids, monoolein and phytantriol, have been formulated to produce lipidic cubic phases and assessed for their use as long acting protein eluting injectables. Three soluble proteins, cytochrome c, glyceraldehyde-3-phosphate dehydrogenase and aldehyde dehydrogenase and one membrane protein, cytochrome c oxidase, were incorporated into bulk cubic phase formulations of each lipid system to comparatively assess protein release kinetics. The activity of the soluble proteins was measured upon release from a phytantriol bulk cubic phase and phytantriol cubosomes, produced using a liquid precursor method.

description: Abstract – The school educational assistant is a professional who intervenes in the learning and socialization processes of pupils with disabilities to enhance their skills in areas such as autonomy and the management of cognitive and relational aspects. Rooted in the Italian policy of “integrazione scolastica”, the educational assistance service has clear purposes and solid regulatory foundations. However, being a service managed and financed by local authorities, it is not carried out in the same way on the national territory. Inevitably, the different organizational choices are reflected in the contexts and educational relations. To stimulate discussion on the subject, a comparison between organizational models of educational assistance is proposed from a perspective that observes their implications in terms of inclusion.

description: We consider the inverse acoustic obstacle problem for sound-soft star-shaped obstacles in two dimensions wherein the boundary of the obstacle is determined from measurements of the scattered field at a collection of receivers outside the object. One of the standard approaches for solving this problem is to reformulate it as an optimization problem: finding the boundary of the domain that minimizes the $L^2$ distance between computed values of the scattered field and the given measurement data. The optimization problem is computationally challenging since the local set of convexity shrinks with increasing frequency and results in an increasing number of local minima in the vicinity of the true solution. In many practical experimental settings, low frequency measurements are unavailable due to limitations of the experimental setup or the sensors used for measurement. Thus, obtaining a good initial guess for the optimization problem plays a vital role in this environment. We present a neural network warm-start approach for solving the inverse scattering problem, where an initial guess for the optimization problem is obtained using a trained neural network. We demonstrate the effectiveness of our method with several numerical examples. For high frequency problems, this approach outperforms traditional iterative methods such as Gauss-Newton initialized without any prior (i.e., initialized using a unit circle), or initialized using the solution of a direct method such as the linear sampling method. The algorithm remains robust to noise in the scattered field measurements and also converges to the true solution for limited aperture data. However, the number of training samples required to train the neural network scales exponentially in frequency and the complexity of the obstacles considered. We conclude with a discussion of this phenomenon and potential directions for future research.
The Dyson Equation with Linear Self-Energy: Spectral Bands, Edges and Cusps

description: We study the unique solution $m$ of the Dyson equation \[ -m(z)^{-1} = z\mathds{1} - a + S[m(z)] \] on a von Neumann algebra $\mathcal{A}$ with the constraint $\mathrm{Im}\, m\ge 0$. Here, $z$ lies in the complex upper half-plane, $a$ is a self-adjoint element of $\mathcal{A}$ and $S$ is a positivity-preserving linear operator on $\mathcal{A}$. We show that $m$ is the Stieltjes transform of a compactly supported $\mathcal{A}$-valued measure on $\mathbb{R}$. Under suitable assumptions, we establish that this measure has a uniformly $1/3$-H\"older continuous density with respect to the Lebesgue measure, which is supported on finitely many intervals, called bands. In fact, the density is analytic inside the bands with a square-root growth at the edges and internal cubic root cusps whenever the gap between two bands vanishes. The shape of these singularities is universal and no other singularity may occur. We give a precise asymptotic description of $m$ near the singular points. These asymptotics generalize the analysis at the regular edges given in the companion paper on the Tracy-Widom universality for the edge eigenvalue statistics for correlated random matrices [J. Alt, L. Erd\H{o}s, T. Kr\" uger, and D. Schr\" oder, Correlated random matrices: Band rigidity and edge universality, Ann. Probab. 48 (2020), no. 2, 963-1001] and they play a key role in the proof of the Pearcey universality at the cusp for Wigner-type matrices [G. Cipolloni, L. Erd\H{o}s, T. Kr\" uger, and D. Schr\" oder, Cusp universality for random matrices, II: The real symmetric case, Pure Appl. Anal. 1 (2019), no. 4, 6154-707, L. Erd\H{o}s, T. Kr\" uger, and D.~Schr\" oder, Cusp Universality for Random Matrices, I: Local Law and the Complex Hermitian Case, Commun. Math. Phys. 378 (2020), no. 2, 1203-1278]. We also extend the finite dimensional band mass formula from [J. Alt, L. Erd\H{o}s, T. Kr\" uger, and D. Schr\" oder, Correlated random matrices: Band rigidity and edge universality, Ann.

description: Distributional identities for a Lévy process $X_t$, its quadratic variation process $V_t$ and its maximal jump processes, are derived, and used to make "small time" (as $t\downarrow0$) asymptotic comparisons between them. The representations are constructed using properties of the underlying Poisson point process of the jumps of $X$. Apart from providing insight into the connections between $X$, $V$, and their maximal jump processes, they enable investigation of a great variety of limiting behaviours. As an application, we study "self-normalised" versions of $X_t$, that is, $X_t$ after division by $\sup_{0

description: Mass timber buildings using cross laminated timber (CLT) and glulam have significantly increased in number globally due to benefits with regards to sustainability as well as other architectural and commercial drivers. This paper presents an introduction and overview of the results from the experimental series CodeRed, highlighting the implications for the engineering design of large open plan mass timber structures. CodeRed is a series of four real scale fire experiments carried out inside a purpose-built, openplan compartment to capture fire dynamics in large compartments with exposed timber. The aim of the CodeRed series was to study the impact on fire dynamics when introducing CLT floors (CodeRed #01), making it intentionally similar to the traveling fire experiments, x-ONE and x-TWO.1, which had a noncombustible ceiling. Additional parameters were studied also, including reduced ventilation (CodeRed #02) and CLT encapsulation (CodeRed #04), by keeping all other parameters the same as CodeRed #01. CodeRed #03 investigated the efficacy of water mist suppression and falls outside the scope of this paper. The experiments showed the reduced ventilation impacts fire dynamics inside and outside the compartment by slowing the fire spread and burning rate. The reduced ventilation in CodeRed #02 led to an increased fire duration 20% longer duration compared to CodeRed #01. The overall fire dynamics experienced in CodeRed #04, corelate with CodeRed #01, x-ONE and x-TWO.1, with a delay in the ignition of the CLT ceiling, as the CLT directly above the crib was encapsulated. Once the CLT ceiling ignited, fire spread rapidly throughout the compartment, with the resulting fire duration, maximum temperatures and heat fluxes broadly similar to CodeRed #01. Long term fire behaviour in the compartment without firefighting intervention was also monitored; smouldering hot spots occurred in the CLT at junctions in CodeRed #01, #02 and #04. The experimental data, observations and findings from this research will assist engineers to understand how exposed mass timber structures impact fire dynamics and apply appropriate solutions for the fire safety design of exposed mass timber buildings.

An affine deformation of the quantum cohomology ring of flag manifolds and periodic Toda lattice

description: Consider the generalized flag manifold $G/B$ and the corresponding affine flag manifold $\mathcal{Fl}_G$. In this paper we use curve neighborhoods for Schubert varieties in $\mathcal{Fl}_G$ to construct certain affine Gromov-Witten invariants of $\mathcal{Fl}_G$, and to obtain a family of "affine quantum Chevalley" operators $Λ_0, \ldots, Λ_n$ indexed by the simple roots in the affine root system of $G$. These operators act on the cohomology ring $\mathrm{H}^*(\mathcal{Fl}_G)$ with coefficients in $\mathbb{Z}[q_0, \ldots,q_n]$. By analyzing commutativity and invariance properties of these operators we deduce the existence of two quantum cohomology rings, which satisfy properties conjectured earlier by Guest and Otofuji for $G= \mathrm{SL}_n(\mathbb{C})$. The first quantum ring is a deformation of the subalgebra of $\mathrm{H}^*(\mathcal{Fl}_G)$ generated by divisors. The second ring, denoted $\mathrm{QH}^*_{\mathrm{af}}(G/B)$, deforms the ordinary quantum cohomology ring $\mathrm{QH}^*(G/B)$ by adding an affine quantum parameter $q_0$. We prove that $\mathrm{QH}^*_{\mathrm{af}}(G/B)$ is a Frobenius algebra, and that the new quantum product determines a flat Dubrovin connection. Further, we develop an analogue of Givental and Kim formalism for this ring and we deduce a presentation of $\mathrm{QH}^*_{\mathrm{af}}(G/B)$ by generators and relations. The ideal of relations is generated by the integrals of motion for the periodic Toda lattice associated to the dual of the extended Dynkin diagram of $G$.

description: We initiate the study of modules of constant Jordan type for quantum complete intersections, and prove a range of basic properties. We then show that for these algebras, constant Jordan type is an invariant of Auslander-Reiten components. Finally, we classify modules with stable constant Jordan type $[1]$ or $[n-1]$ in the 2-generator case.

The Universal Lie $\infty$-Algebroid of a Singular Foliation

Publisher: name: Deutsche Mathematiker-Vereinigung
Year: 2020

description: We consider singular foliations ${\cal F}$ as locally finitely generated $ {\mathscr O}$-submodules of $ {\mathscr O}$-derivations closed under the Lie bracket, where ${\mathscr O}$ is the ring of smooth, holomorphic, or real analytic functions on a correspondingly chosen manifold. We first collect and/or prove several results about the existence of resolutions of such an ${\cal F}$ in terms of sections of vector bundles. For example, these exist always on a compact smooth manifold $M$ if ${\cal F}$ admits real analytic generators. We show that every complex of vector bundles $(E_\bullet,\dd)$ over $M$ providing a resolution of a given singular foliation ${\cal F}$ in the above sense admits the definition of brackets on its sections such that it extends these data into a Lie $\infty$-algebroid. This Lie $\infty$-algebroid, including the chosen underlying resolution, is unique up to homotopy and, moreover, every other Lie $\infty$-algebroid inducing the given ${\cal F}$ or any of its sub-foliations factors through it in an up-to-homotopy unique manner. We therefore call it the universal Lie $\infty$-algebroid of ${\cal F}$. It encodes several aspects of the geometry of the leaves of ${\cal F}$. In particular, it permits us to recover the holonomy groupoid of Androulidakis and Skandalis. Moreover, each leaf carries an isotropy Lie $\infty$-algebra structure that is unique up to isomorphism. It extends a minimal isotropy Lie algebra, that can be associated to each leaf, by higher brackets, which give rise to additional invariants of the foliation. As a byproduct, we construct an example of a foliation ${\cal F}$ generated by $r$ vector fields for which we show by these techniques that, even locally, it cannot result from a Lie algebroid of the minimal rank $r$.

description: Data-driven predictive control based on the fundamental lemma by Willems et al. is frequently considered for deterministic LTI systems subject to measurement noise. However, little has been done on data-driven stochastic control. In this paper, we propose a data-driven stochastic predictive control scheme for LTI systems subject to possibly unbounded additive process disturbances. Based on a stochastic extension of the fundamental lemma and leveraging polynomial chaos expansions, we construct a data-driven surrogate Optimal Control Problem (OCP). Moreover, combined with an online selection strategy of the initial condition of the OCP, we provide sufficient conditions for recursive feasibility and for stability of the proposed data-driven predictive control scheme. Finally, two numerical examples illustrate the efficacy and closed-loop properties of the proposed scheme for process disturbances governed by different distributions.

First order flow for non-extremal AdS black holes and mass from holographic renormalization

description: In this paper we present a first order formulation for non-extremal Anti-de Sitter black hole solutions in four dimensional $\mathcal{N}=2$ U(1)-gauged Supergravity. The dynamics is determined in terms of a quantity $\mathcal{W}$ which plays the role of a superpotential for the gauging potential in the action. We show how the first order flow arises from writing the action as a sum of squares and we identify the superpotential driving the first order flow for two classes of solutions (electric and magnetic) of the $t^3$ model. After identifying $\mathcal{W}$, we study the Hamilton-Jacobi holographic renormalization procedure in presence of mixed boundary conditions for the scalar fields. We compute the renormalized on-shell action and the mass of the black hole configurations. The expression obtained for the mass satisfies the first law of thermodynamics.

description: Abstract – Which role should the school play in high socio-cultural complexity contexts? And concerning the extraschool contexts? Which perspective of community and society formal and non-formal education contexts should follow? These questions represent the basis of the article. The aim of the essay is to suggest some reflections on the role of the educational contexts in order to offer to each child the possibility to express himself/herself, hopefully becoming equal and inclusive educating communities. Riassunto – In contesti educativi ad elevata complessità sociale, culturale, linguistica, ecc. quale ruolo dovrebbe assumere la scuola? E l’extra-scuola?

Questi ed altri interrogativi costituiscono le basi del presente articolo, in cui si intendono proporre alcune riflessioni in merito al ruolo dei contesti educativi (formali e non formali) nel provare a essere contesti in cui tutti e tutte possano avere l’opportunità di esprimere sé stessi diventando così, auspicabilmente, delle comunità educanti eque ed inclusive. Keywords – heterogeneous education contexts, school contexts, extra-school contexts, education poverty and inclusion, educating communities Parole chiave – contesti educativi eterogenei, scuola, extra-scuola, povertà educativa e inclusione, comunità educanti

description: We show a homological result for the class of planar or symmetric operad groups: We show that under certain conditions, group (co)homology of such groups with certain coefficients vanishes in all dimensions, provided it vanishes in dimension $0$. This can be applied for example to $l^2$-homology or cohomology with coefficients in the group ring. As a corollary, we obtain explicit vanishing results for Thompson-like groups such as the Brin-Thompson groups $nV$.
