We especially encourage the participation of young researchers, who will benefit from interactions with the invited speakers and other senior researchers. In particular, we invite young researchers to present their work at the poster session. Invited speakers: Stefan Adams (Warwick), Alessandra Bianchi (Padova), Oriane Blondel (Lyon), Nicoletta Cancrini (Roma), Emilio Cirillo (Roma), Pierre Collet (Palaiseau), Loren Coquille (Grenoble), Ivan Corwin (New York), Anna De Masi (L Aquila), Béatrice de Tilière (Paris), Alessandra Faggionato (Roma),Hubert Lacoin (Rio de Janeiro), Roberto Livi (Firenze), Christian Maes (Leuven), Fabio Martinelli (Roma), Stefano Olla (Paris), Elisabetta Scoppola (Roma), Senya Shlosman (Marseille), Aernout van Enter (Groningen).

Seminario di Pietro Rigo a Bologna
by Massimo Campanino 13 Mar '19

13 Mar '19

Il giorno venerdì 22 marzo alle ore 14:30 nell'Aula Seminario 2 del Dipartimento di Matematica dell'Università di Bologna, piazza Porta S. Donato 5, il prof. Pietro Rigo del Dipartimento di Matematica dell'Università di Pavia terrà un seminario dal titolo: On the existence of continuous processes with given one-dimensional distribution Abstract: Let $\mathcal{P}$ be the collection of Borel probability measures on $\mathbb{R}$, equipped with the weak* topology, and let $\mu:[0,1]\rightarrow\mathcal{P}$ be a continuous map. Say that $\mu$ is presentable if $X_t\sim\mu_t$, $t\in [0,1]$, for some real process $X$ with continuous paths. It may be that $\mu$ fails to be presentable. Conditions for presentability are given in this note. For instance, $\mu$ is presentable if $\mu_t$ is supported by an interval for all but countably many $t$. In addition, assuming $\mu$ presentable, we investigate whether there is a continuous process $X$ with the same finite dimensional distributions as the quantile process $Q$ induced by $\mu$. The latter is defined, on the probability space $((0,1),\mathcal{B}(0,1),\,$Lebesgue measure$)$, by \begin{gather*} Q_t(\alpha)=\inf\,\bigl\{x\in\mathbb{R}:\mu_t(-\infty,x]\ge\alpha\bigl\}\quad\quad\text{for all }t\in [0,1]\text{ and }\alpha\in (0,1). \end{gather*} Various open problems are stated as well.

Seminario di Paolo Dai Pra a Bologna
by Massimo Campanino 13 Mar '19

13 Mar '19

Il giorno venerdì 22 marzo alle ore 12 nell'Aula Seminario 2 del Dipartimento di Matematica dell'Università di Bologna, piazza Porta S. Donato 5, il prof. Paolo Dai Pra del Dipartimento di Matematica dell'Università di Padova terrà un seminario dal titolo: Thermodynamic limit and phase transitions in non-cooperative games: some mean-ﬁeld examples Abstract: In stochastic dynamics inspired by Statistical Mechanics the interaction between diﬀerent particles, or agents, is usually expressed as a given function of their states. The behavior of the system, in the limit of inﬁnitely many particles (thermodynamic limit), may change dramatically by small changes in the parameters of the model: when this occurs we say there is a phase transition. In many applications the interaction cannot be given a priori but it is rather a result of agents’ strategy, aimed at optimizing a given performance. Using the simplest models of this nature, mean ﬁeld games, we illustrate some examples of phase transitions, pointing to diﬃculties in the proof of the thermodynamic limit.

A``WINTER'' DAY IN PROBABILITY AND STATISTICAL PHYSICS: 22 Marzo 2019 (Gallavotti e Rolles)
by Francesca Romana Nardi 12 Mar '19

12 Mar '19

Siamo felici di annunciarvi la settima giornata di seminari: A ``WINTER'' DAY IN PROBABILITY AND STATISTICAL PHYSICS University of Florence Friday 22 March 2019 Lecturers: Giovanni Gallavotti (Roma) and Silke Rolles (Munich) Location: Aula Tricerri Viale Morgagni 67, Firenze Informazionei su come arrivare alla pagina: https://www.dimai.unifi.it/vp-285-come-arrivare-how-to-get.html Prof. Giovanni Gallavotti (Universita` di Roma La Sapienza) Title: Title: Statistical ensembles, entropy and probability in statistical mechanics, and extension to chaotic motions. Abstract: A historical view on the theoretical developments generated by Boltzmann's attempt to find a mechanical interpretation of the second principle, from the action principle to the Boltzmann's equation to phase transitions and their universality to the modern developments in the non-equilibrium thermodynamics. In the second part the case of fluid mechanics and an interpretation of viscosity and irreversibility will be analyzed and related to an extension of the statistical ensembles to non-equilibrium phenomena. Prof. Silke Rolles (Technical University of Munich) Title: Processes with reinforcement. Abstract: In 1986, Persi Diaconis introduced edge-reinforced random walk as a simple model for a tourist exploring an unknown city. Already then, he raised the question of recurrence and transience of this process on the d-dimensional integer lattice. Since edge-reinforced random walk is more likely to traverse edges that have been traversed often before and simple random walk is recurrent in dimension 2, recurrence of edge-reinforced random walk on the two-dimensional integer lattice may seem intuitively clear. However, a proof of this result was only found in 2015 by Sabot and Zeng. For dimensions larger or equal to 3 a phase transition between recurrence and transience was shown by Disertori, Sabot and Tarres in 2011 and 2014. In the talk I will give an overview of the subject and present some basic techniques. In particular, the edge-reinforced random walk is a mixture of reversible Markov chains with an explicitly known mixing measure. In a special case, this can be illustrated with an analogous result for the Polya urn. Program: 11.00-11.45 Introductory lecture: Gallavotti 11.45-12.00 Break 12.00-12.45 Seminar: Gallavotti 13.00-14.30 Lunch 14.30-15.15 Introductory lecture: Rolles 15.15-15.30 Break 15.30-16.30 Seminar: Rolles Organizers: G.

Summer School "Equilibria in Financial Markets: General Equilibrium and Game Theoretic Perspective" - Bielefeld University, July 08 - July 12, 2019.
by Giorgio Ferrari 12 Mar '19

12 Mar '19

Dear All, this is a kind reminder announcing the Summer School *"Equilibria in Financial Markets: General Equilibrium and Game Theoretic Perspective"* to be held at *Bielefeld University* in the week *July 08 - July 12, 2019*. http://www.uni-bielefeld.de/(en)/imw/summerschool19/ During the summer school we aim at discussing the different approaches to "equilibrium" arising in financial markets and games. In particular, we intend to discuss recent advances in general equilibrium theory, stochastic games of control and stopping, backward stochastic differential equations in games and general equilibrium, and mean-field games. These topics will be addressed during the lectures of *Luciano Campi (London School of Economics)* *Saïd Hamadène (Université du Maine) <http://lmm.univ-lemans.fr/spip.php?article6>* *Kasper Larsen (Rutgers School of Arts and Sciences) * *Gordan Zitkovic (university of Texas at Austin) * *Frank Riedel (Bielefeld University)* *Deadline for applications* is *April 30, 2019*, and you can apply through the following link http://www.uni-bielefeld.de/(en)/imw/summerschool19/application/index.html* * Looking forward to having you in Bielefeld, Giorgio Ferrari* * --- Questa e-mail è stata controllata per individuare virus con Avast antivirus. https://www.avast.com/antivirus

de Finetti risk seminar - march 2019
by Emanuela Rosazza 11 Mar '19

11 Mar '19

On behalf of the Scientific Committee of the de Finetti Risk Seminars, we are glad to invite you to participate at the following Lecture Entropic and dynamic optimal transport Giuseppe Savaré Dipartimento di Matematica “Felice Casorati”, Università di Pavia Abstract: We will briefly review various equivalent characterizations of Optimal Transport and we will show that a simple relaxation of its Benamou-Brenier dynamic formulation leads to the new class of Optimal Entropy- Transport problems, combining entropic and transport costs. We will discuss the particular example of the Hellinger-Kantorovich metric, which provides a natural geometric way to measure the distance between positive measures with possibly different masses. LOCATION: The seminar will be held on Wednesday, March 13, at 18.00 at room 3-E4-SR03, Bocconi University, Via Rontgen 1, 3rd floor, Milano. A refreshment will be offered at 17.30. Scientific Committee: Prof. Simone Cerreia-Voglio (Univ. Bocconi) Prof. Marco Frittelli (Univ. degli Studi di Milano) Prof. Fabio Maccheroni (Univ. Bocconi) Prof. Massimo Marinacci (Univ. Bocconi) Prof. Emanuela Rosazza Gianin (Univ. Milano-Bicocca) Dott.
