Seminar Alessandra Bianchi at Tor Vergata 16.10
by Michele Salvi 09 Oct '24

09 Oct '24

Dear all, On Wednesday, October 16th, at 14h00 in Aula D'Antoni of Tor Vergata Math Department, RoMaDS (https://www.mat.uniroma2.it/~rds/events.php) will host Alessandra Bianchi (University of Padova) with the seminar "Mixing cutoff for simple random walks on the Chung-Lu directed graph” Abstract: In this talk, we consider a simple random walk defined on a Chung-Lu directed graph, an inhomogeneous random network that extends the Erdos Renyi random digraph by including edges independently according to given Bernoulli laws. In this non-reversible setting, we will focus on the convergence toward the equilibrium of the dynamics. In particular, under the assumption that the average degree grows logarithmically in the size n of the graph (weakly dense regime), we will establish a cutoff phenomenon at the entropic time of order log(n)/loglog(n). We will then show that on a precise window the cutoff profile converges to the Gaussian tail function. This is qualitatively similar to what was proved in a series of works by Bordenave, Caputo, Salez for the directed configuration model, where degrees are deterministically fixed. In terms of statistical ensembles, this analysis provides an extension of these cutoff results from a hard to a soft-constrained model. Joint work with G. Passuello. We encourage in-person partecipation.

Seminario di Bertram Duering in Sapienza
by Enrico Scalas 08 Oct '24

08 Oct '24

Car* collegh*, Il 19 novembre 2024, in aula 24 del Dipartimento di Scienze Statistiche, Sapienza, Università di Roma, alle ore 14, il Prof. Bertram Düring della University of Warwick, Mathematics Institute terrà un seminario dal titolo From interacting agents to emerging patterns in economics and sociology Riassunto: Real-world systems in economics and sociology often consist of a large number of interacting agents that may form patterns or develop a collective behaviour. Typical applications include wealth and income distribution in an economy and opinion formation in a society. Mathematical techniques originating from statistical mechanics can be successfully developed further to model such systems and obtain mesoscopic and macroscopic descriptions of the microscopic dynamics. Such approaches frequently lead to generalisations of the classical Boltzmann equation for gas dynamics and associated limit partial differential equations. In this talk I will discuss different kinetic models for wealth distribution and opinion formation, and present analytical and numerical results. Tutte le persone interessate sono invitate a partecipare. Chi fosse interessato a partecipare a distanza, per favore, mi scriva a: enrico.scalas(a)uniroma1.it Cordiali saluti, Enrico Scalas

Seminari on-line del gruppo UMI - PRISMA (http://www.umi-prisma.polito.it/) Ricordiamo che oggi, martedì 8 ottobre 2024, Giovanni Conforti (Università di Padova) e Giacomo Greco (Università di Roma Tor Vergata) parleranno di Una passeggiata sui ponti di Schrödinger: dalla meccanica statistica all’algoritmo di Sinkhorn con il seguente orario: 16:00 Primo seminario 16:30 Pausa e discussione 16:45 Secondo seminario 17:15 Conclusione e discussione Trovate di seguito il riassunto. I seminari verranno trasmessi via Zoom al seguente link: https://uniroma1.zoom.us/j/88679569146 Meeting ID: 886 7956 9146 Vi aspettiamo numerosi! Valentina Cammarota e Francesco Caravenna %%%%%%%%%%%%%%%%%%%%%%%%%%%% RELATORI: Giovanni Conforti (Università di Padova) e Giacomo Greco (Università di Roma Tor Vergata) TITOLO: Una passeggiata sui ponti di Schrödinger: dalla meccanica statistica all’algoritmo di Sinkhorn. RIASSUNTO: Nel 1931, E.Schrödinger si interessò al problema di calcolare l’evoluzione più probabile di una nube di particelle Browniane indipendenti condizionatamente all’osservazione della loro configurazione agli istanti iniziale e finale. In linguaggio moderno, questo problema, detto problema di Schrödinger, viene formulato rigorosamente attraverso la teoria delle grandi deviazioni come un problema di minimizzazione entropica con vincoli marginali. Molti anni dopo, T.Mikami scoprì che il problema di Schrödinger converge verso il problema del trasporto ottimo, detto di Monge-Kantorovich, nel limite di rumore piccolo. Questo collegamento, che permette di vedere il problema di trasporto entropico come una regolarizzazione del problema deterministico, è stato largamente sfruttato negli ultimi anni nel contesto dello statistical machine learning. Il motivo principale di questo interesse è che il problema del trasporto entropico si può risolvere con un algoritmo veloce e di facile implementazione, l’algoritmo Sinkhorn. Tale algoritmo, introdotto negli anni '60, richiede solamente alcune semplici operazioni tra matrici, come la moltiplicazione componente per componente: in particolare, non è necessaria alcuna inversione di matrice. Dal punto di vista teorico, l’attrattiva principale risiede nella convergenza esponenziale nel numero di iterazioni. Tuttavia, la comprensione di questo fenomeno è ancora incompleta, per esempio nel caso base del costo quadratico, e più in generale per problemi di trasporto con costi non limitati e marginali a supporto non compatto. Anche per misure discrete, ci sono ancora numerose questioni aperte, per esempio riguardo alla dipendenza del tasso di convergenza dal parametro di regolarizzazione. L’obiettivo della prima parte di questo seminario è di introdurre il problema di Schrödinger come problema di meccanica statistica, esporre il collegamento con il problema di Monge Kantorovich, e introdurre l’algoritmo di Sinkhorn. Nella seconda parte il seminario si concentrerà sul problema della convergenza esponenziale, offrendo una panoramica su risultati più o meno recenti e le diverse tecniche di dimostrazione, e presentando alcune domande aperte. %%%%%%%%%%%%%%%%%%%%%%%%%%%% I seminari PRISMA hanno un formato di "colloquium" per creare un'occasione di scambio e discussione con tutta la comunità dei probabilisti e statistici italiani. Ogni giornata comprende due relatori che tengono due seminari di 30 minuti strettamente connessi, per presentare alla comunità una prospettiva sul proprio ambito di ricerca. Da quest'anno le registrazioni dei seminari vengono pubblicate sul canale YouTube dell'UMI: https://youtube.com/playlist?list=PLmySpc-jrtAMq84VH71evyqPc1hl6eEQb %%%%%%%%%%%%%%%%%%%%%%%%%%%%

mini-course on "Computability and Computational Complexity Questions in Dynamics"
by Stefano Marmi 07 Oct '24

07 Oct '24

Prof. Michael Yampolsky (University of Toronto) will give a series of 4 lectures on "Computability and Computational Complexity Questions in Dynamics" at the Scuola Normale Superiore in Pisa. The lectures will take place on Thursday October 24 and 31 and November 7 and 14, at 2:30 pm in Aula Volterra, in Piazza dei Cavalieri 7. The titles and abstracts of each of the 4 lectures are given below. Please contact me if you have any questions. Stefano Marmi stefano.marmi(a)sns.it 1) October 24: Computability and computational complexity in dynamics: can we trust numerical predictions of limiting behavior of orbits? The development of the modern subject of dynamical systems went hand-in-hand with numerical modeling. However, the theoretical basis of such modeling has remained largely unexplored and offers exciting challenges. What can and cannot be computed about the behavior of a dynamical system? I will give an overview of some of the recent results and directions of study. 2) October 31: Don’t believe your lying eyes: (non)-computability of Julia sets The talk will be a deep dive into the question of computability and computational complexity of Julia sets. Their fractal images are among the most-computed pictures in all of mathematics. But can we trust what these computations show? The results are surprising, and involve some beautiful complex analysis. The talk will be based on my work with M. Braverman, as well as more recent results obtained with A. Dudko, C. Rojas, and others. 3) November 7: How to lose at Monte Carlo: computing statistical behavior of dynamical systems Introduced by Ulam and von Neumann in the 1940s, Monte Carlo technique remains the most ubiquitous tool for statistical modeling. Surprisingly, our recent work with C. Rojas shows that such modeling provably fails for some very simple dynamical systems. I will present this theorem and discuss the resulting mathematical challenges. 4) November 14: Thurston versus Turing: algorithmic hardness of classifying finite dynamical systems Historically, the algorithmic aspects of classification problems have motivated much of the research in geometric topology (knot theory, classification of surfaces and 3-manifolds, etc). These questions are also very fruitful in dynamics. I will discuss the joint results with N. Selinger, K. Rafi and others on algorithmic decidability of Thurston equivalence and the connection with geometrization questions in dynamics.

First Lucia Workshop on Fractional Calculus and Processes in Växjö, Sweden
by Lorenzo CRISTOFARO 03 Oct '24

03 Oct '24

Dear colleagues, The Lucia celebration on December 13 is one of the most important Swedish traditions. Processions of white-clad Lucias and their followers bear candles and sing songs to bring light in the Scandinavian winter. Saffron buns and mulled wine (glögg) are also part of the celebration. From December 9-December 13, 2024 we will organize the First Lucia Workshop on Fractional Calculus and Processes at the Linnæus University in Växjö, Sweden. Please visit the conference webpage for more information: https://lnu.se/en/meet-linnaeus-university/current/events/2024/lufcap2024/ The main goal of the workshop is to bring together the best specialists in various fields of fractionality and fractality. The results of the workshop will be published in a special issue of MSTA. If you are inclined to participate it would be great if you can let us know until October 15. Please indicate if you want to contribute a talk (email to (wolfgang.bock(a)lnu.se<mailto:wolfgang.bock@lnu.se>)). The participation of the workshop will be free of charge. Though some funding is available and we are working hard to acquire more it would be very helpful for our planing if you could indicate whether you would be needing some support from our side. We can of course not guarantee a travel support at the moment. With warm regards, Wolfgang Bock, Chirstian Engström, Elmira Nabizadeh and Yuliya Mishura

Seminario Dieter Mitsche, Martedì 8 Ottobre, Sapienza Università di Roma
by Silvestri, Vittoria 02 Oct '24

02 Oct '24

Segnalo il seguente seminario, che si terrà Martedì prossimo in Sapienza. *Martedì 8 Ottobre, ore 14:00* Sala di Consiglio, Dipartimento di Matematica, Sapienza Università di Roma *Speaker:* Dieter Mitsche (Pontificia Universidad Católica de Chile) *Title: *Component sizes in spatial random graphs *Abstract:* We consider a large class of spatially-embedded random graphs that includes among others long-range percolation, continuum scale-free percolation and the age-dependent random connection model. We assume that the parameters are such that there is an infinite component. We identify the stretch-exponent $\zeta$ of the subexponential decay of the cluster-size distribution. That is, with $|\CC(0)|$ denoting the number of vertices in the component of the vertex at $0\in \R^d$, we prove $ P (k\le |\CC(0)|<\infty)=\exp\big(-\Theta(k^{\zeta})\big), $ as $k$ tends to infinity. The value of $\zeta$ undergoes several phase transitions with respect to three main model parameters: the Euclidean dimension $d$, the power-law tail exponent $\tau$ of the degree distribution and a long-range parameter $\alpha$ governing the presence of long edges in Euclidean space. Joint work with Joost Jorritsma and Julia Komjáthy. ******************************** Vittoria Silvestri Assistant Professor Department of Mathematics University "La Sapienza" Piazzale Aldo Moro, 5 00185 - Rome ********************************

Seminar Andriy Olenko at Tor Vergata 09.10
by Michele Salvi 02 Oct '24

02 Oct '24

Dear all, On Wednesday, October 9th, at 14h00 in Aula Dal Passo of Tor Vergata Math Department, RoMaDS (https://www.mat.uniroma2.it/~rds/events.php) will host Andriy Olenko (La Trobe University Melbourne) with the seminar "Limit theorems for multifractal products of random fields” Abstract: We will discuss the asymptotic properties of multifractal products of random fields. The obtained limit theorems provide conditions for the convergence of cumulative fields in $L_q$ spaces. New results concerning the rate of convergence of cumulative fields will also be presented. Simple, unified conditions for the limit theorems and the calculation of the Rényi function are provided, which are even less restrictive than those found in existing one-dimensional results. The developed methodology is further applied to multidimensional multifractal measures. Finally, a new class of examples based on geometric sub-Gaussian random fields will be introduced. In this case, the general assumptions take a simple form and can be expressed solely in terms of covariance functions. This presentation is based on joint work with I. Donhauzer (La Trobe University). We encourage in-person partecipation. Should you be unable to come, here is the link to the Teams streaming: https://teams.microsoft.com/l/meetup-join/19%3arfsL73KX-fw86y1YnXq2nk5VnZFw… The seminar is part of the Excellence Project MatMod@TOV.

9 Oct 2024 - Seminar Anna Fiori
by Enea Bongiorno 02 Oct '24

02 Oct '24

Carissimi colleghi, scusandomi per eventuali invii multipli, vi inoltro il seguente annuncio di seminario. Tutti gli interessati sono invitati a partecipare. Cordialmente, Enea Bongiorno -------------------------------- - when: 9 October 2024, at 16.15 - where: room 206, campus Perrone, via Perrone, 18, Novara. Università del Piemonte Orientale. - on-line: meet.google.com/eic-tuux-rzh Title: *Compositional methods and capital allocation: a proposal * *Speaker: **Anna Fiori, Università degli Studi di Milano-Bicocca* *Abstract*: The capital allocation problem of an insurance company relates to the decomposition of an aggregate risk capital into additive contributions corresponding to different risk sources (e.g., individual agents, business units, specific guarantees included in a set of contracts). The proportions of risk capital allocated to each part can be viewed as quantitative descriptions of the components of a whole, subject to a fixed sum constraint (full allocation). This interpretation suggests interesting connections between capital allocation principles and Compositional Data (CoDa) analysis. The purpose of this work is to introduce a novel allocation framework that prioritizes the compositional perspective. In particular, we propose an optimality criterion based on a (modified) compositional distance between relative losses and capital shares allocated to them. In this way, we explicitly recognize that the relevant information associated with risks arising from –and resources assigned to– each constituent part is indeed information relative to a total. Different from previous research on compositional capital allocations, our approach is not restricted to gradient allocation rules or specific risk measures like VaR or CVaR. We propose instead a general reformulation of the optimal capital allocation problem which is inherently consistent with the relative scale of compositional variables. The resulting capital allocation solutions are compared to other proposals in recent literature and evaluated empirically on a dataset of cyber losses. ----------------------------------- Locandina dell'evento <https://drive.google.com/file/d/1kKe_GZFJ4rnsTJ4PlOGTxDWs6dYYModv/view?usp=…> Seminari Matematici Statistici <https://seminari-ms.uniupo.it/home-page> ----------------------------------- -- Enea G.

Seminar Dario Spanò @LUISS
by Alessia Caponera 30 Sep '24

30 Sep '24

Dear all, The Department of Economics and Finance at LUISS University in Rome (*https://economiaefinanza.luiss.it <https://economiaefinanza.luiss.it/>*) is pleased to announce the following seminar: *Speaker*: Dario Spanò, Warwick University *Title*: *Dualities and Intertwinings in the Two-Parameter Poisson-Dirichlet Diffusion* *When*: October 3rd, 12:00 *Where*: Viale Romania, 32 00197 Rome *Meeting room*: TD2 AB *Abstract*: Mathematical population genetics has been an incredible culture broth for the recent developments of the modern theory of stochastic duality. Duality in genetics clarifies the intrinsic link between forward-in-time dynamics of a population’s allele frequencies evolution and backward-in-time dynamics of the same population’s ancestry. I will show that a duality with very much the same genetic ancestral structure can be established for an infinite-dimensional diffusion – the Two-parameter Poisson-Dirichlet diffusion – helping significantly the tractability of such processes for simulation and inference. *Webpage*: https://economiaefinanza.luiss.it/research-seminar/dualities-and-intertwini… *Should you be interested, please kindly send me an email.* Best wishes, Alessia Caponera

Seminario Christian Hirsch - Politecnico di Milano - 10 Ottobre 2024
by Luca Scarpa 30 Sep '24

30 Sep '24

Si segnala il seguente seminario a tutti gli interessati. Giovedì 10 Ottobre 2024, ore 14:30. Aula Seminari III Piano, Dipartimento di Matematica, Politecnico di Milano. Speaker: Christian Hirsch, Aarhus University. Title: Large deviations of one-hidden-layer neural networks. Abstract: In this talk, I will present large deviations in the context of stochastic gradient descent for one-hidden-layer neural networks with quadratic loss. I will explain how to derive quenched and annealed large deviation principle for the empirical weight evolution during training when letting the number of neurons and the number of training iterations simultaneously tend to infinity. The weight evolution is treated as an interacting dynamic particle system. The distinctive aspect compared to prior work on interacting particle systems lies in the discrete particle updates, simultaneously with a growing number of particles. This talk is based on joint work with Daniel Willhalm.
