Buongiorno Lunedì 1 aprile, ore 10:30-13:00, aula B, Dipartimento di Matematica La Sapienza ci sara' il primo incontro del corso di dottorato di Fabio Toninelli (in cui verra' anche stabilito l'orario definitivo). Il corso si svolgerà durante il mese di aprile. sotto trovate dettagli del corso. saluti alessandra faggionato %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Fabio Toninelli (University Lyon 1) The dimer model: equilibrium and non-equilibrium aspects Abstract. This course focuses on various mathematical aspects of lattice dimer models. These are very classical two-dimensional statistical mechanics models, that are exactly solvable in some sense (Kasteleyn, 1961): partition function and correlations can be computed in determinantal form. Recently there has been a new wave of interest in dimer models, both in probability, combinatorics and mathematical physics. One reason is that these models, as well as other two-dimensional critical models, exhibit conformal invariance properties. Another interesting aspect is that they allow to obtain very nice Markov dynamics of two-dimensional interfaces, whose large-scale dynamical behavior can be studied. Detailed contents: • Kasteleyn theory (partition functions, correlations, determinantal properties) • correlations and representation determinantale • thermodynamic limit and ergodic Gibbs measures • height fluctuations and massless Gaussian field • dynamics of dimer models: mixing time and hydrodynamic limits.

Seminar announcement
by Marco Scarsini 22 Mar '19

22 Mar '19

Thursday, 28 March, 12:00 Room 204 Luiss Viale Romania, 32 00197 Roma Paul Dütting, London School of Economics and Political Science Prophet inequalities for independent random variables from an unknown distribution Abstract: A central object in optimal stopping theory is the single-choice prophet inequality for independent, identically distributed random variables: Given a sequence of random variables X_1,…,X_n drawn independently from a distribution F, the goal is to choose a stopping time τ so as to maximize α such that for all distributions F we have E[X_τ] ≥ α⋅E[max_t X_t]. What makes this problem challenging is that the decision whether τ = t may only depend on the values of the random variables X_1,…,X_t and on the distribution F. For quite some time the best known bound for the problem was α ≥ 1−1/e ≈ 0.632 [Hill and Kertz, 1982]. Only recently this bound was improved by Abolhassani et al. [2017], and a tight bound of α ≈ 0.745 was obtained by Correa et al. [2017]. The case where F is unknown, such that the decision whether τ = t may depend only on the values of the first t random variables but not on F, is equally well motivated (e.g., [Azar et al., 2014]) but has received much less attention. A straightforward guarantee for this case of α ≥ 1/e ≈ 0.368 can be derived from the solution to the secretary problem. Our main result is that this bound is tight. Motivated by this impossibility result we investigate the case where the stopping time may additionally depend on a limited number of samples from F. An extension of our main result shows that even with o(n) samples α ≤ 1/e, so that the interesting case is the one with Ω(n) samples. Here we show that n samples allow for a significant improvement over the secretary problem, while O(n^2) samples are equivalent to knowledge of the distribution: specifically, with n samples α ≥ 1−1/e ≈ 0.632 and α ≤ ln(2) ≈ 0.693, and with O(n^2) samples α ≥ 0.745−ε for any ε > 0.

de Finetti risk seminar
by Emanuela Rosazza 21 Mar '19

21 Mar '19

Gentile Prof. Cambini, Le sarei grata se potesse inoltrare il seguente avviso di messaggio. La ringrazio anticipatamente e saluto cordialmente, Emanuela --- On behalf of the Scientific Committee of the de Finetti Risk Seminars, we are glad to invite you to participate at the following Lecture A mathematical model of learning reward uncertainty in the brain Rafal Bogacz Nuffield Department of Clinical Neurosciences, University of Oxford Abstract: To maximise their chances for survival, humans and animals need to base their decisions not only on the average consequences of chosen actions, but also on the variability of the rewards resulting from these actions. For example, when ones food reserves are depleted, one should prefer to forage in an area where food is guaranteed, rather than an area where the amount of food is higher on average but variable, thus avoiding the risk of starvation. To implement such policies, the brain needs to be able to learn about variability of rewards resulting from taking different actions. This talk will present a simple mathematical model describing how such learning may be implemented in the brain. The models suggests how the information about reward uncertainty is used by the brain to make decisions that not only maximize expected rewards but also take risks into account. The models is consistent with a wide range of experimental data from neuroscience. The talk will also include a discussion of the relationship between the model and the probability weighting functions from the prospect theory. LOCATION: The seminar will be held on Wednesday, March 27, at 15.00 at room 3-E4-SR03, Bocconi University, Via Rontgen 1, 3rd floor, Milano. A refreshment will be offered at 14.45.

Seminario di Paolo Di Tella a Tor Vergata
by Anna Vidotto 19 Mar '19

19 Mar '19

Dear all, I would like to announce the following talk that will be held on Friday, April 5th 2019, at 4:30 PM, in Aula D’Antoni of the Department of Mathematics, University of Rome Tor Vergata, in the framework of the activities supported by the MIUR Excellence Department Project CUP E83C18000100006. Speaker: Paolo Di Tella Title: On The Weak Representation Property in Progressively Enlarged Filtrations with an Application in Exponential Utility Maximization Abstract: In this talk we show that the weak representation property of a semimartingale $X$ with respect to a filtration $\mathbb{F}$ is preserved in the progressive enlargement $\mathbb{G}$ by a random time $\tau$ avoiding $\mathbb{F}$-stopping times and such that $\mathbb{F}$ is immersed in $\mathbb{G}$. As an application of this, we can solve an exponential utility maximization problem in the enlarged filtration $\mathbb{G}$ following the dynamical approach, based on suitable BSDEs, both over the fixed-time horizon $[0,T]$, $T>0$, and over the random-time horizon $[0,T\wedge\tau]$.

Workshop on Random Dynamical Systems and Anomalous Dynamics, Londra 20-22 Marzo 2019
by Enrico Scalas 18 Mar '19

18 Mar '19

Car* collegh*, se siete a Londra dal 20 al 22 marzo, vi puo' interessare questo workshop che si terra' all'Imperial College organizzato da Yuzuru Sato, Rainer Klages e Jeroen Lamb: http://lml.org.uk/event/workshop-on-random-dynamical-systems-and-anomalous-… Workshop aim: This workshop brings together theoretical physicists and mathematicians working on dynamical systems and stochastic processes. An emphasis is on the recent active fields of random dynamical systems and anomalous stochastic dynamics. The former refers to chaotic dynamical systems that are coupled to noise. This combination can create novel phenomena such as anomalous diffusion, stochastic bifurcations, and varieties of noise-induced phenomena. To describe them requires a new mathematical language defining objects such as random attractors, perturbed invariant measures, bifurcations, and rare event statistics. Anomalous dynamics denotes processes whose mean square displacement, unlike that of Brownian motion, grows non-linearly in time. They exhibit non-trivial properties related to non-Gaussian probability distributions, such as power-law decay of correlations, sub- or super-diffusion and ergodicity breaking. However, the emergence of such phenomena from deterministic dynamics is poorly understood. By bridging the gap between the dynamical systems and applied stochastic processes communities we aim to advance this understanding. Cordiali saluti, Enrico Scalas

Seminario di Stefano Pagliarani a Pisa
by Dario Trevisan 15 Mar '19

15 Mar '19

Cari colleghi, annuncio il seguente seminario che si terrà lunedì 25 marzo, alle 14:00, nella Sala Seminari presso il dipartimento di Matematica dell'università degli studi di Pisa. Dear colleagues, I would like to announce the following talk that will be held on Monday, 25 March 2019, at 2 PM, in Sala Seminari, Department of Mathematics, University of Pisa. #### Speaker: Stefano Pagliarani (Università degli studi di Udine) Title: Contraction methods for a class of McKean-Vlasov (mean-field) SDEs with jumps. Abstract: We consider two prototype classes of McKean-Vlasov (mean-field) SDEs with jumps. In the first case, the coefficient is assumed to be affine in the state-variable, only measurable in the law, and the dynamics allow for Lévy jumps. We study the equivalent functional fixed-point equation for the unknown time-dependent coefficients of the associated Markovian SDE. By proving a contraction property for the functional map in a suitable normed space, we infer existence and uniqueness results for the MK-V SDE, and derive a discretized Picard iteration method that approximates the law of the solution. Numerical illustrations show the effectiveness of the method, which appears to be appropriate to handle multi-dimensional settings. We finally describe possible extensions and generalizations to more general settings. The second class of MKV SDEs that we consider allows for self-exicitng jumps, which amounts to having jumps through hitting the boundary in the equivalent large particle system. The corresponding PDE problem is a particular instance of free-boundary problems known as supercooled Stefan-like problems. We write a Volterra equation for the free boundary and prove contraction results that are useful to determine the properties of the solution and to provide convergent numerical schemes. -- Dario Trevisan, Università degli Studi di Pisa, Dipartimento di Matematica, Largo Bruno Pontecorvo 5, 56127 - Pisa (PI) Italy telephone: (+39) 050 2213832 mobile: (+39) 331 2899761 Skype: dario-trevisan e-mail: dario.trevisan AT unipi.it webpage: http://people.dm.unipi.it/trevisan/

Seminario di Pietro Rigo a Bologna
by Massimo Campanino 14 Mar '19

14 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.

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

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)

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.

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
