description: In 2007, and in a series of later papers, Joy Christian claimed to refute Bell's theorem, presenting an alleged local realistic model of the singlet correlations using techniques from Geometric Algebra (GA). Several authors published papers refuting his claims, and Christian's ideas did not gain acceptance. However, he recently succeeded in publishing yet more ambitious and complex versions of his theory in fairly mainstream journals. How could this be? The mathematics and logic of Bell's theorem is simple and transparent and has been intensely studied and debated for over 50 years. Christian claims to have a mathematical counterexample to a purely mathematical theorem. Each new version of Christian's model used new devices to circumvent Bell's theorem or depended on a new way to misunderstand Bell's work. These devices and misinterpretations are in common use by other Bell critics, so it useful to identify and name them. I hope that this paper can serve as a useful resource to those who need to evaluate new "disproofs of Bell's theorem". Christian's fundamental idea is simple and quite original: he gives a probabilistic interpretation of the fundamental GA equation a.b = (ab + ba)/2. After that, ambiguous notation and technical complexity allow sign errors to be hidden from sight, and new mathematical errors can be introduced.

description: Climate change threatens to disrupt human communities and lifestyles globally. Coastal areas in particular face sea-level rise and storm surge issues. Identifying design procedures for climate change design could promote successful implementation and long-term sustainability. Based on existing literature, a set of design criteria is formed to guide the implementation of nature-based design in response to projected sea-level rise in East Potomac Park in Washington, D.C. The design criteria address socio-ecological factors of landscape, planning and design for adaptation and resilience, communicating climate change, and design performance evaluation. The design criteria inform a site design focused on adapting with projected sea-level rise. The design is cross-evaluated with the criteria for robustness. The project connects research with practice by creating a design-science feedback loop and provides a platform for innovative solutions in climate change design in national parks and other landscapes threatened by issues of sea-level rise.

description: When formulated in twistor space, the D-instanton corrected hypermultiplet moduli space in N=2 string vacua and the Coulomb branch of rigid N=2 gauge theories on $R^3 \times S^1$ are strikingly similar and, to a large extent, dictated by consistency with wall-crossing. We elucidate this similarity by showing that these two spaces are related under a general duality between, on one hand, quaternion-Kahler manifolds with a quaternionic isometry and, on the other hand, hyperkahler manifolds with a rotational isometry, further equipped with a hyperholomorphic circle bundle with a connection. We show that the transition functions of the hyperholomorphic circle bundle relevant for the hypermultiplet moduli space are given by the Rogers dilogarithm function, and that consistency across walls of marginal stability is ensured by the motivic wall-crossing formula of Kontsevich and Soibelman. We illustrate the construction on some simple examples of wall-crossing related to cluster algebras for rank 2 Dynkin quivers. In an appendix we also provide a detailed discussion on the general relation between wall-crossing and the theory of cluster algebras.

C-sortable words as green mutation sequences

subject: FOS: Mathematics

description: Let $Q$ be an acyclic quiver and $\mathbf{s}$ be a sequence with elements in the vertex set $Q_0$. We describe an induced sequence of simple (backward) tilting in the bounded derived category $\mathcal{D}(Q)$, starting from the standard heart $\mathcal{H}_Q=\operatorname{mod}\mathbf{k}Q$ and ending at another heart $\mathcal{H}_\mathbf{s}$ in $\mathcal{D}(Q)$. Then we show that $\mathbf{s}$ is a green mutation sequence if and only if every heart in this simple tilting sequence is greater than or equal to $\mathcal{H}_Q[-1]$; it is maximal if and only if $\mathcal{H}_\mathbf{s}=\mathcal{H}_Q[-1]$. This provides a categorical way to understand green mutations. Further, fix a Coxeter element $c$ in the Coxeter group $W_Q$ of $Q$, which is admissible with respect to the orientation of $Q$. We prove that the sequence $\widetilde{\mathbf{w}}$ induced by a $c$-sortable word $\mathbf{w}$ is a green mutation sequence. As a consequence, we obtain a bijection between $c$-sortable words and finite torsion classes in $\mathcal{H}_Q$. As byproducts, the interpretations of inversions, descents and cover reflections of a $c$-sortable word $\mathbf{w}$ are given in terms of the combinatorics of green mutations.

description: We present a quantum Monte Carlo study of the "quantum glass" phase of the 2D Bose-Hubbard model with random potentials at filling $ρ=1$. In the narrow region between the Mott and superfluid phases the compressibility has the form $κ\sim {\rm exp}(-b/T^α)+c$ with $α<1$ and $c$ vanishing or very small. Thus, at $T=0$ the system is either incompressible (a Mott glass) or nearly incompressible (a Mott-glass-like anomalous Bose glass). At stronger disorder, where a glass reappears from the superfluid, we find a conventional highly compressible Bose glass. On a path connecting these states, away from the superfluid at larger Hubbard repulsion, a change of the disorder strength by only $10\%$ changes the low-temperature compressibility by more than four orders of magnitude, lending support to two types of glass states separated by a phase transition or a sharp cross-over.

description: We studied the dimension-6 leptonic anomalous gauge couplings in the formulation of linearly realized gauge symmetry effective Lagrangian and investigated the constraints on these anomalous couplings from the existed experimental data including LEP2 and $W$/$Z$ boson decay. Some bounds of $O(0.1-10){\rm TeV}^{-2}$ on four relevant anomalous couplings are given by the Z factories. We studied the sensitivity of testing the leptonic anomalous couplings via the process $e^+e^-\rightarrow W^+W^-$ at future $e^+e^-$ linear colliders. We discussed different sensitivities to anomalous couplings at polarized and unpolarized $e^+e^-$ colliders, respectively, with 500 GeV and 1 TeV collision energy. Our results show that the a 500 GeV ILC can provide a test of the anomalous couplings, with the same relative uncertainty of cross section measurement, of $O(0.1-1){\rm TeV}^{-2}$, and a 1 TeV ILC can test the anomalous couplings of $O(0.01-0.1){\rm TeV}^{-2}$.

description: We show that the recent experimental realization of spin-orbit coupling in ultracold atomic gases can be used to study different types of spin spiral order and resulting multiferroic effects. Spin-orbit coupling in optical lattices can give rise to the Dzyaloshinskii-Moriya (DM) spin interaction which is essential for spin spiral order. By taking into account spin-orbit coupling and an external Zeeman field, we derive an effective spin model in the Mott insulator regime at half filling and demonstrate that the DM interaction in optical lattices can be made extremely strong with realistic experimental parameters. The rich finite temperature phase diagrams of the effective spin models for fermions and bosons are obtained via classical Monte Carlo simulations.

description: Following the end of the coronavirus pandemic, the European Central Bank (ECB) was confronted with an unprecedented increase in energy prices. This led to consumer price inflation in the euro area far beyond the ECB’s inflation target of two percent, at times up to 10 percent. At the same time, the euro area economy was threatened by a recession, which resulted in the ECB facing conflicting objectives of stabilizing the economy and combating inflation. Estimates show that while the ECB’s policy strategy of maintaining a low level of interest rates did improve the economy, it also exacerbated the rise in energy prices. The empirical analysis demonstrates that an interest rate hike at the beginning of the energy crisis would have stabilized inflation more effectively. Tightening monetary policy would have curbed energy demand and caused the euro to appreciate, which would have led to a more rapid decline in energy prices. In this counterfactual scenario, the euro area would have had to endure a brief recession, but the overall economic situation would have stabilized by the fourth quarter of 2023. The ECB would likely have been better able to follow its price stability mandate if a capital markets and fiscal union existed in the euro area.

description: Strumenti di comunicazione delle élite socio-economiche, i quotidiani italiani dell’Ottocento dedicano ben poco interesse alle espressioni musicali del ‘popolo’ e di altre culture. Su tali espressioni, tutt’al più, si trovano brevi osservazioni e commenti all’interno di cronache locali, oppure sporadici articoli, sovente con tono di divertissement. Si tratta comunque di materiali che criticamente verificati, alla luce anche delle conoscenze di altre fonti letterarie ed iconografiche coeve (diari di viaggiatori, testi etnografici ante litteram eccetera), possono offrire indicazioni sul paesaggio sonoro dell’epoca e sulle narrazioni connesse con l’attività musicale. Su questa base, il saggio focalizza un piccolo corpus di materiali schedati nella banca dati Artmus e ricavati da giornali della Sardegna. Al di là dei contenuti, tali materiali presentano tracce significative sul sorgere della questione dell’identità culturale dell’isola, e sull’immaginario esotico condiviso dagli uomini colti e delle classi sociali agiate del tempo.

description: Elevated dispositional negativity (DN; i.e., neuroticism/negative emotionality) is associated with a range of deleterious outcomes, including mental illness. Yet, DN’s neurobiology remains incompletely understood. Prior work suggests that DN reflects heightened threat-elicited reactivity in the extended amygdala (EAc), a circuit encompassing the central nucleus (Ce) and the bed nucleus of the stria terminalis (BST), and that this association may be intensified for uncertain threat. We utilized a multi-trait, multi-occasion DN composite and neuroimaging assays of threat anticipation and perception to demonstrate that individuals with elevated DN show heightened BST activation during threat anticipation. Analyses revealed that DN is uniquely predicted by BST reactivity to uncertain threat. DN was unrelated to Ce activation during threat anticipation or EAc activation during ‘threatening’-face presentation. Follow-up analyses revealed that the threat paradigms are not interchangeable probes of EAc function. These observations lay the foundation for future studies necessary to determine causation and improve interventions.

description: Subjective well-being is essential for both quality of life and a healthy society. Studies have shown that satisfied people have better relationships, are more productive, and have a longer life expectancy. General life satisfaction is being discussed as an alternative measure of prosperity beyond GDP. Thus, findings on this topic are relevant for both the scientific community as well as policymakers. This Weekly Report investigates the income, work, and health satisfaction of the German population from 2004 to 2021. Using data from the Socio-Economic Panel, we investigate if there are differences in satisfaction between genders, regions (east/west), age groups, parental status, and income groups. The analysis shows that general life satisfaction as well as income, work, and health satisfaction have either increased or remained constant since 2004. However, differences between groups, some quite significant, still remain, especially in terms of health satisfaction. Comparatively, low-income earners and parents are dissatisfied. To counter this, policy measures to unburden parents and improve the childcare system are needed.

description: The pace of thermal retrofit of buildings in Germany remains slow. A Worst-First approach, prioritizing the retrofit of inefficient buildings, would address energy- and social policy objectives and deliver economic and climate benefits. Data from the German Socio-Economic Panel (SOEP) show how such an approach would protect especially low-income households often living in very inefficient buildings from heating costs risks. This group comprises 28 percent of all tenants and 13 percent of all homeowners. Yet, uncertainty about the cost-benefit of retrofitting and other priorities of homeowners mean that not enough buildings are retrofitted. As a result, the saving potentials, especially from very inefficient buildings, are not being realized. This would, however, be necessary to reduce heating cost risks and energy import dependency, and to meet climate targets. Better alignment of financing and subsidy instruments with the ownership structure, the further development of building standards to include minimum energy performance standards, and reform of tenancy law could improve the situation.

description: In this work we describe a method to reconstruct the braid monodromy of the preimage of a curve by a Kummer cover. This method is interesting, since it combines two techniques, namely, the reconstruction of a highly non-generic braid monodromy with a systematic method to go from a non-generic to a generic braid monodromy. This "generification" method is independent from Kummer covers and can be applied in more general circumstances since non generic braid monodromies appear more naturally and are oftentimes much easier to compute. Explicit examples are computed using these techniques.

«Sulla via di Benedetto Marcello»: il discorso sui ‘classici’ nei quotidiani di Firenze Capitale
Creators: name: D'Ovidio, Antonella
Publisher: name: Pavia University Press - Edizioni dell'Università degli Studi di Pavia
Year: 2021

description: L’articolo ricostruisce un episodio di microstoria, finora dimenticato, della vita musicale della Firenze ottocentesca, rileggendolo alla luce dei cambiamenti politici, sociali e culturali traumatici, che investono la città all’indomani della sua proclamazione come Capitale provvisoria del Regno d’Italia. Si tratta del progetto della ripresa e «continuazione» dell’Estro poetico armonico di Benedetto Marcello, finanziato dal patrizio fiorentino Simone Vincenzo Velluti Zati e da lui affidato nel 1865 a Antonio Bazzini e Ferdinando Giorgetti. Il progetto fu promosso da personalità come Abramo Basevi e da critici musicali come Girolamo Alessandro Biaggi e Francesco D’Arcais. I documenti relativi a questa iniziativa e gli interventi pubblicati da Biaggi e D’Arcais su «La Nazione» e «L’Opinione» fanno comprendere come l’intreccio tra realtà municipale e dimensione nazionale si ripercuota anche sul discorso attorno alla musica e alla vita musicale fiorentina portato avanti dalla stampa quotidiana di quegli anni. Il ‘ritorno’ a Marcello voluto dal Duca e il discorso sulla necessità dei ‘classici’ continuamente proposto dai quotidiani assumono il valore di una ricerca identitaria collettiva che coinvolge la vita musicale, così come l’immagine e la percezione stessa della città.

description: Refugees have limited health care entitlements during the asylum process. In February 2024, the maximum length of this exclusion period was increased from 18 to 36 months. This increase may double the actual waiting time, which is currently already more than one year, as data from the Socio-Economic Panel show. This particularly affects refugees with a low level of education and little knowledge of German. A longer waiting time not only negatively impacts the health of affected individuals but is also disadvantageous for the state; late treatment often requires more expensive treatment. Thus, shortening the period would have been more sensible than increasing it. The electronic health insurance card (EHIC) for refugees makes access to health services during this waiting period easier, as it reduces administrative barriers. However, just under 20 percent of all refugees have an EHIC, as the system has not been introduced in all federal states. The electronic health insurance card should be introduced nationwide in order to cushion the negative effects of extended restrictions on health care.

description: Novel segmentation algorithms can easily identify objects that are occludedor partially occluded, however in highly cluttered scenes the degree of occlusion is so high that some objects may not be visible to a static camera. In these scenarios, humans use action to change the configuration of the environment, elicit more information through perception, process the information before taking the next action. Reinforcement learning models this behavior, however unlike humans, the phase where perception data is understood is not included, as images are directly used as observations. The aim of this thesis is to establish a novel method that indirectly uses perception data for reinforcement learning to address the task of decluttering a scene using a static camera.
Public participation to estimate forest fuels loading : the development and testing of an application for remote sensing
Creators: name: Ferster, Colin Jay
Publisher: name: University of British Columbia
Year: 2014

description: Advances in mobile computing provide an increasing number of possibilities for public participation in scientific research (PPSR). For example, a growing number of people have access to mobile computing devices, such as smartphones, equipped with sensors including a camera, global positioning system, the ability to record observations, and the ability transfer them over a network for collection and analysis. Literature has shown that PPSR-based approaches can have positive outcomes for volunteers (e.g., opportunities to pursue interests, develop skills, and influence decisions), for resource management (by providing data to inform management strategies), and for science. The objective of this dissertation is to explore how volunteers can use smartphones to collect data to inform forest management in a remote sensing project. The management of wildfires in communities near forested areas was chosen as a case study, and a smartphone application was developed and tested for collecting observations of the amount and arrangement of forest fuels by participants with a range of forestry experience living in fire-affected communities. First, to establish context, other projects using smartphones to collect Earth observation data were reviewed including related terms, concepts, challenges, and opportunities to identify methods of data collection and data processing. Second, questionnaires were given to the volunteers before and after using the application to collect data and were analyzed to understand the social and management considerations including the volunteers’ motivations, attitudes, and behaviours, and the potential of using a PPSR approach for wildfire management. Third, the locations where volunteers submitted data were re-measured and the quality of the data were assessed to provide guidelines for ensuring attribute accuracy and logical consistency. Fourth, the smartphone data was combined with multispectral remote sensing data and topography data to make estimates over broader areas. Finally, a framework was presented to direct future efforts using volunteered remote sensing data. This dissertation demonstrates an approach with potential to apply technology to help inform forest management in communities, with potentially positive outcomes for volunteers, communities, and forest managers.

The first one is given in a similar fashion to Chas-Sullivan's string topology. The second one is defined on the Hochschild homology associated with a cyclic, multiplicative operad of graded modules. The latter can be applied to Bousfield-Salvatore spectral sequence converging to the homology of the space of framed long knots. Conjecturally these two structures coincide with each other.

description: L’arrivo dell’operetta di Offenbach in Italia nel secondo Ottocento portò nuova linfa vitale al comparto teatrale, contribuendo in modo decisivo all'affermazione del teatro musicale leggero. In città quali Milano e Napoli l’effetto prodotto dalle rappresentazioni di operette offenbachiane fu immediato, giacché a partire dalla seconda metà degli anni Sessanta si assiste alla proliferazione di nuove forme spettacolari ispirate proprio a quel modello. Il contributo, oltre ad analizzare il rapporto tra operetta e tradizione locale attraverso i due casi emblematici di Milano e Napoli, mette in luce le ricadute di questo genere sull’intero sistema produttivo nazionale e soprattutto sul cammino dell’opera comica.

description: The German economy will likely contract in the first quarter of 2024 due to still heightened inflation and weak demand, which was already weighing on German economic output in 2023. Inflation, which is falling in both Germany and the euro area overall, is expected to return close to the European Central Bank's two-percent target, suggesting that a turnaround in interest rates can be expected in early summer. Better financing conditions and the slowdown in price momentum are likely to somewhat boost both private consumption as well as corporate investments over the course of 2024. Nevertheless, there is currently still a great deal of uncertainty, particular in regard to the future economic policy environment, which is causing households and companies to remain cautious in Germany. In addition, fiscal policy stimuli as well as foreign demand are lacking. German GDP will virtually stagnate and, carried by private consumption and public investments in equipment, increase more markedly by 1.2 percent in 2025. The global economy will continue to develop more robustly than Germany; it is projected to increase by 3.5 percent in both 2024 and 2025, which should gradually strengthen German exports.

description: Here the gravitational lensing in strong field limit of a Schwarzschild black hole with a solid deficit angle owing to global monopole within the context of the $f(R)$ gravity theory is investigated. We obtain the expressions of deflection angle and time delay in the forms of elliptic integrals and discuss the asymptotic behaviour of the elliptic integrals to find the explicit formulae of angle and time difference in the strong field limit. We show that the deflection angle and the time delay between multiple images are related not only to the monopole but also to the $f(R)$ correction $ψ_{0}$ by taking the cosmological boundary into account. Some observables such as the minimum impact parameter, the angular separation, the relative magnification and the compacted angular position have been estimated as well. It is intriguing that the tiny modification on the standard general relativity will make the remarkable deviation on the angle and the time lag, offering a significant way to explore some possible distinct signatures of the topological soliton and the correction of the Einstein general relativity.

description: In this paper we advance physical background of the energy- and flux-budget turbulence closure based on the budget equations for the turbulent kinetic and potential energies and turbulent fluxes of momentum and buoyancy, and a new relaxation equation for the turbulent dissipation time-scale. The closure is designed for stratified geophysical flows from neutral to very stable and accounts for the Earth rotation. In accordance to modern experimental evidence, the closure implies maintaining of turbulence by the velocity shear at any gradient Richardson number Ri, and distinguishes between the two principally different regimes: "strong turbulence" at Ri << 1 typical of boundary-layer flows and characterised by the practically constant turbulent Prandtl number; and "weak turbulence" at Ri > 1 typical of the free atmosphere or deep ocean, where the turbulent Prandtl number asymptotically linearly increases with increasing Ri (which implies very strong suppression of the heat transfer compared to the momentum transfer). For use in different applications, the closure is formulated at different levels of complexity, from the local algebraic model relevant to the steady-state regime of turbulence to a hierarchy of non-local closures including simpler down-gradient models, presented in terms of the eddy-viscosity and eddy-conductivity, and general non-gradient model based on prognostic equations for all basic parameters of turbulence including turbulent fluxes.

Effettismo e verosimiglianza nell’opera italiana del secondo Ottocento

description: Sulla scorta di diverse tipologie di fonti, il contributo mette a fuoco i molti mutamenti sopraggiunti nel teatro musicale italiano in epoca postunitaria, che investono aspetti diversi del sistema produttivo e ricettivo: dall’appartenenza sociale del pubblico alla strutturazione degli spazi deputati ad accoglierlo, dai soggetti d’opera alla morfologia dei libretti, dalla sintassi musicale fino alle modalità della messinscena e alla gestualità dei cantanti. A differenza delle opinioni espresse da Verdi circa la necessità di una drammaturgia musicale non timorosa delle censure dei critici ma allo stesso tempo neppure succuba degli orientamenti di gusto degli spettatori, gli operisti di secondo Ottocento (tra questi: Ponchielli, Gomes, Boito) tendono ad andare incontro alla ‘cultura mezzana’ del pubblico, propendendo per drammi a tinte forti, esasperazione di passioni, estremizzazione dei contrasti, ricerca di effetti, sfarzo di scenografie e costumi.

Counting genus zero real curves in symplectic manifolds

description: There are two types of $J$-holomorphic spheres in a symplectic manifold invariant under an anti-symplectic involution: those that have a fixed point locus and those that do not. The former are described by moduli spaces of $J$-holomorphic disks, which are well studied in the literature. In this paper, we first study moduli spaces describing the latter and then combine the two types of moduli spaces to get a well-defined theory of counting real curves of genus 0. We use equivariant localization to show that these invariants (unlike the disk invariants) are essentially the same for the two (standard) involutions on $\mathbb{P}^{4n-1}$.

description: It is sometimes speculated that the sign problem that afflicts many quantum field theories might be reduced or even eliminated by choosing an alternative domain of integration within a complexified extension of the path integral (in the spirit of the stationary phase integration method). In this paper we start to explore this possibility somewhat systematically. A first inspection reveals the presence of many difficulties but - quite surprisingly - most of them have an interesting solution. In particular, it is possible to regularize the lattice theory on a Lefschetz thimble, where the imaginary part of the action is constant and disappears from all observables. This regularization can be justified in terms of symmetries and perturbation theory. Moreover, it is possible to design a Monte Carlo algorithm that samples the configurations in the thimble. This is done by simulating, effectively, a five dimensional system. We describe the algorithm in detail and analyze its expected cost and stability. Unfortunately, the measure term also produces a phase which is not constant and it is currently very expensive to compute. This residual sign problem is expected to be much milder, as the dominant part of the integral is not affected, but we have still no convincing evidence of this. However, the main goal of this paper is to introduce a new approach to the sign problem, that seems to offer much room for improvements. An appealing feature of this approach is its generality. It is illustrated first in the simple case of a scalar field theory with chemical potential, and then extended to the more challenging case of QCD at finite baryonic density.

description: The persistent, unambiguous identification of data objects is now recognized as a necessary and central component of modern data infrastructure, especially in an interdisciplinary context. Registered persistent identifiers work to allow machines and humans to understand which digital object is in question (identity), what it is (category or type), and where it is (location). Each of these questions is surprisingly fraught and complex. This presentation begins to explore how a socio-geographical perspective can help us begin to address that complexity and answer those seemingly basic questions. We explore how issues of data identity are very dependent on the context in which the data are perceived. Using Susan Leigh Star’s concept of “boundary objects” — objects that are part of multiple social worlds and facilitate communication between them — we examine how data and even their identifiers can be adaptable to different interpretations and categorizations. The idea with a boundary object is to reduce local uncertainty without damaging cooperation, where representations of data and identity support multiple interpretations and purposes across intersecting worlds without a shared consensus. We further draw from human geographic concepts of borderlands and feminist ideas of intersectionality to illustrate new ways of considering how data is managed, described, and presented. We close with examples of how these socio-geographic considerations can pragmatically guide decisions in the development of standards and data infrastructure ranging from specific details around metadata management and data formats to more holistic considerations, such as community development and standards uptake.
Random walks in cones

description: We study the asymptotic behavior of a multidimensional random walk in a general cone. We find the tail asymptotics for the exit time and prove integral and local limit theorems for a random walk conditioned to stay in a cone. The main step in the proof consists in constructing a positive harmonic function for our random walk under minimal moment restrictions on the increments. For the proof of tail asymptotics and integral limit theorems, we use a strong approximation of random walks by Brownian motion. For the proof of local limit theorems, we suggest a rather simple approach, which combines integral theorems for random walks in cones with classical local theorems for unrestricted random walks. We also discuss some possible applications of our results to ordered random walks and lattice path enumeration.

description: Il saggio affronta il tema del dibattito ottocentesco che oppone in un primo tempo la musica italiana a quella tedesca, per precisarsi in seguito come opposizione Verdi vs Wagner, in modo particolare nell’ambito del movimento della Scapigliatura e dei suoi dintorni. Di quest’ultimo si prende in considerazione (con citazioni dai suoi articoli) un noto giornalista, Leone Fortis, finora poco analizzato negli studi sul dibattito wagneriano in Italia. Per il periodo successivo (anni Novanta), sempre in merito al caso Wagner italiano, il contributo cita e commenta passi di un romanzo di Arturo Colautti, steso negli anni in cui infuria in Italia la ‘battaglia’ tra verdiani e wagneriani.
