Seminar by Dr. Piero Mazzarisi.
by Giorgio Rizzini 24 Feb '23

24 Feb '23

Dear all, we are glad to announce the following seminar by Dr. Piero Mazzarisi (University of Siena) on Tuesday, February 28th 2023 starting from 11:00 in room 4026 at the Department of Statistics and Quantitative Methods, University of Milano-Bicocca (Milan). *Realized Random Graphs, with an application to the Interbank Network* *Piero Mazzarisi* Department of Economics and Statistics University of Siena *Abstract:* This work introduces a new econometric methodology to infer dynamic network models driven by latent state variables. The main idea is to obtain a noisy representation of the state variables dynamics by computing a sequence of cross-sectional estimates of the network model at each point in time. The dynamic modeling of these cross-sectional estimates, that we name realized random graphs, transforms the original nonlinear state-space network model into a linear time-series model that can easily be estimated. Under the assumption that the network is dense, and of a mixed-membership blockmodel structure, we show that the model parameters and the unobservable state variables can be estimated at a super-consistent rate of convergence for large cross sections. By allowing for an extremely rich parameterization of the model in high dimensions, the proposed methodology describes the heterogeneous topology of real-world networks. We corroborate our findings by using this novel framework to estimate and forecast the dynamic common factors driving the evolution of the Italian electronic market of interbank deposits. *February 28th, 2023, 11:00 a.m.* *Department of Statistics and Quantitative Methods* Aula Seminari 4026 - Building U7 (Fourth floor*)* *Bicocca degli Arcimboldi street, 8 – 20126 Milan* For further information, please write to *rosanna.grassi(a)unimib.it <rosanna.grassi(a)unimib.it>*

SPASS Seminars: M. Aleandri and M. Rehmeier
by Francesco Grotto 21 Feb '23

21 Feb '23

Dear Colleagues, We would like to invite you to the following SPASS seminar by Marco Rehmeier (U. Bielefeld) and Michele Aleandri (Sapienza), jointly organized by UniPi, SNS, UniFi and UniSi. The seminars will take place on TUE, 28.2.2023 starting at 14:00 CET in Sala Seminari, Dipartimento di Matematica, Pisa. The seminars will also be broadcasted on Google Meet, follow the link below for the streaming. The organizers, A. Agazzi, G. Bet, A. Caraceni, F. Grotto, G. Zanco https://sites.google.com/unipi.it/spass Marco Rehmeier (Bielefeld University), 14:00 Title: On nonlinear Markov Processes in the sense of McKean Abstract: We study nonlinear Markov processes in the sense of McKean and present a large new class of examples. Our notion of nonlinear Markov property is in McKean's spirit, but more general in order to include examples of such processes whose one-dimensional time marginals solve a nonlinear parabolic PDE, such as Burgers' equation, the porous media equation, or variants of the latter with transport-type drift. We show that the associated nonlinear Markov process is given by path laws of weak solutions to a corresponding distribution-dependent stochastic differential equation whose coefficients depend singularly (i.e. Nemytskii-type) on its one-dimensional time marginals. Moreover, we show that also for general nonlinear Markov processes, their path laws are uniquely determined by one-dimensional time marginals of suitable associated conditional path laws. Furthermore, we characterize the extremality of the curves of the one-dimensional time marginals of our nonlinear Markov Processes in the class of all solutions to the associated linearized PDE and, this way, obtain new interesting results also for the classical linear case. This is joint work with Michael Röckner. Michele Aleandri (Università di Roma La Sapienza), 15:00 Title: Opinion dynamics with Lotka-Volterra type interactions Abstract: We investigate a class of models for opinion dynamics in a population with two interacting families of individuals. Each family has an intrinsic mean field “Voter-like” dynamics which is influenced by interaction with the other family. The interaction terms describe a cooperative/conformist or competitive/nonconformist attitude of one family with respect to the other. We prove chaos propagation, i.e., we show that on any time interval [0; T], as the size of the system goes to infinity, each individual behaves independently of the others with transition rates driven by a macroscopic equation. We focus in particular on models with Lotka-Volterra type interactions, i.e., models with cooperative vs. competitive families. For these models, although the microscopic system is driven a.s. to consensus within each family, a periodic behaviour arises in the macroscopic scale. In order to describe fluctuations between the limiting periodic orbits, we identify a slow variable in the microscopic system and, through an averaging principle, we find a diffusion which describes the macroscopic dynamics of such variable on a larger time scale.

However, the estimators are constructed in different ways for different parameters. Then we consider the numerical estimation of the drift parameter in the linear model with two fBms with different Hurst indices. Numerical construction of MLE is reduced to the numerical solution of the Fredholm integral equation of the 2nd kind with a singular kernel.

Next OWPS on March 1st: Alan Hammond and Tyler J. Helmuth
by Alberto Chiarini 20 Feb '23

20 Feb '23

OWPS's next session will be on Wednesday the 1s of March of from 15:00 to 17:00 UTC. Our next speakers are: Alan Hammond (Berkeley) and Tyler J. Helmuth (Durham University) Title, abstract and the zoom link are below the signature and can be found on the website https://www.owprobability.org/one-world-probability-seminar. We have found that many that subscribed to the mailing list to receive these updates are not receiving them anymore. If you are interested in the project, we kindly ask you to resubscribe to the mailing list and share this announcement within your community. With best wishes, Alberto Chiarini (Padua) and Adrián González Casanova (Berkeley and México) ----------------------------------------------------------------------------------------------------------- Talk 1 : Alan Hammond (Berkeley) Title : Stake-governed random-turn games Abstract : Many combinatorial games, such as chess, Go and Hex, are zero-sum games in which two players alternate in making moves. In a random turn variant, each player wins the right to move at any given turn according to the flip of a fair coin. In 2007, Peres, Schramm, Sheffield and Wilson [PSSW] found explicit optimal strategies for a broad class of random-turn games, including Hex (which remains unsolved in its alternating-turn form on the 11-by-11 boards in which it is often played in tournaments). In this talk, we discuss stake-governed random-turn games, introduced recently in joint work with Gábor Pete. Two players of Hex are each given a certain limited budget at the outset of the game. At each turn, each stakes some part of what remains of her budget. The ensuing turn is random, with a player winning the right to move according to the proportion that her stake composes of the total stake at the turn. How much should a player stake at any given turn? Opposing pressures compete: stake too little, and lose the turn; too much, and be left with too little for later in the game. So this question concerns how to evaluate the relative strategic importance of intermediate positions in multi-turn games. We answer it for a class of games that are cousins of the random tug-of-war games introduced by PSSW in 2009; these authors forged a connection between game theory and the infinity Laplacian (which is an L^\infty counterpart to the usual L^2 Laplacian), and we will see how, in a discrete context at least, this connection extends to stake-governed random-turn games. Talk 2 : Tyler J. Helmuth (Durham University) Title : The Arboreal Gas Abstract : In Bernoulli bond percolation each edge of a graph is declared open with probability p, and closed otherwise. Typically one asks questions about the geometry of the random subgraph of open edges. The arboreal gas is the probability measure obtained by conditioning on the event that the percolation subgraph is a forest, i.e., contains no cycles. Physically, this is a model for studying the gelation of branched polymers. What are the percolative properties of these random forests? Do they contain giant trees? I will discuss what is known and conjectured.

Mi presento
by Marco Zamparo 20 Feb '23

20 Feb '23

Buongiorno a tutti, da qualche ora sono parte di questa vostra lista. Questo breve messaggio è per presentarmi a quelli di voi che ancora non mi conoscono. Mi chiamo Marco Zamparo e sono un fisico teorico "pentito" che da qualche anno si occupa di probabilità e fisica statistica rigorosa. Allego un CV aggiornato per i curiosi. Sto lavorando al modello di pinning dei polimeri con Giambattista Giacomin (Université Paris Cité) e ai processi di rinnovo in ambiente random con Frank den Hollander (Universiteit Leiden). Sono inoltre interessato allo studio del gas di Lévy-Lorentz, del quale ho parzialmente caratterizzato le proprietà di trasporto. Ho un RTDA in fisica teorica e sono in cerca di una posizione in probabilità o fisica matematica per poter completare la "trasformazione". Dati i vincoli Gelmini sugli anni di precariato, sono costretto a considerare solo RTDB o nuovi RTT. Sono in possesso dell'abilitazione scientifica nazionale in fisica matematica (MAT/07) e a maggio chiederò quella in probabilità (MAT/06). Se qualcuno avesse piacere di conoscermi, sarei lieto di fare una presentazione o un seminario. Non vi rubo altro tempo. Grazie per l'attenzione! Buona settimana, Marco

OWPS Tomorrow: Frank den Hollander and Elena Pulvirenti
by Alberto Chiarini 14 Feb '23

14 Feb '23

Dear all, A reminder that tomorrow (Wednesday), from 15:00 to 17:00 UTC, Frank den Hollander and Elena Pulvirenti will be speaking at the One World Probability Seminar. Titles, abstracts and the zoom link are below the signature and will also be posted on the website https://www.owprobability.org/one-world-probability-seminar. We kindly ask for your help to share this message within your community. Best wishes, Alberto Chiarini and Adrián González Casanova ---------------------- Speakers: Frank den Hollander (Leiden) and Elena Pulvirenti (Delft) Talk 1 : Metastability for the Widom-Rowlinson model: I. Planar discs. Abstract We define the static Widom-Rowlinson model on a two-dimensional finite torus. The energy of a particle configuration is determined by its halo, defined as the union of unit discs centred at the positions of the particles. We discuss the metastable behaviour of a dynamic version of the model, in which particles are randomly created and annihilated as if the outside of the torus were an infinite reservoir with a given chemical potential. We start with the empty torus and are interested in the first time when the torus is fully covered by unit discs. This can be viewed as the crossover time from a ‘gas phase’ to a ‘liquid phase’. We consider the metastable regime where the temperature is low and the chemical potential is supercritical. In order to achieve the transition from empty to full, the system needs to create a sufficiently large droplet, called critical droplet, which triggers the crossover. It turns out that the critical droplet is close to a disc of a certain deterministic radius, with a boundary that is random and consists of a large number of unit discs that stick out by a small distance. We show how an analysis of the surface fluctuations allows us to derive both a volume term and a surface term in the asymptotics of the average crossover time. Based on joint work with Sabine Jansen (Munich) and Roman Kotecký (Prague). Talk 2 : Metastability for the Widom-Rowlinson model: II. Grains of general shape. Abstract We investigate what happens when the planar discs are replaced by convex grains in arbitrary dimensions whose shape may be random. We identify the size and the shape of the critical droplet as a function of the shape distribution for the grains. We also identify the volume term in the asymptotics of the average crossover time. In addition, we speculate about the surface term, formulating a conjecture about what it should look like. There are various interesting subcases, showing that the shape of the grains has a rather delicate influence on the critical droplet and the average crossover time. Based on joint work with Yogesh Dhandapani (Bangalore) and Roman Kotecký (Prague).

When graphs are sparse the picture is less clear, objects that describe globally the graphs and their limits, as graphons do for dense graphs, have not been defined yet. Nevertheless we do have information on how these graphs look like when explored locally from a vertex and this, under some assumptions, gives also information on global properties. In this talk we will give an overview on what is known on rare events in this regime, focusing in particular on large deviation statements on connected components in inhomogeneous random graphs and on links with coagulation processes. This talk is based on joint works with Wolfgang König (WIAS and TU Berlin), Tejas Iyer, Heide Langhammer, Elena Magnanini and Robert Patterson (WIAS).
