Francesco Russo's talk at the Torino seminar series in Stochastics and Mathematical Statistics
by Tiziano De Angelis 29 Sep '21

29 Sep '21

Dear all, We are glad to announce the first seminar of the *Torino seminar series in Stochastics and Mathematical Statistics. * Torino seminar series SMS is a monthly seminar series held at the Department of Mathematics G. Peano of the University of Turin. For more info and a list of future talks see https://sites.google.com/view/torinostochastics. *Date and time:** Friday 1 October*, 2021, h 17:00-18:00 *Location*: Aula Magna, Palazzo Campana, via Carlo Alberto 10, Torino *Speaker*: *Francesco RUSSO *(ENSTA Paris, Institut Polytechnique de Paris) *Title*: Fokker-Planck equations with terminal condition and related McKean probabilistic representation *Abstract**:* Stochastic differential equations (SDEs) in the sense of McKean are stochastic differential equations, whose coefficients do not only depend on time and on the position of the solution process, but also on its marginal laws. Often they constitute probabilistic representation of conservative PDEs, called Fokker-Planck equations; In general Fokker-Planck PDEs are well-posed if the initial condition is specified. Here, alternatively, we consider the inverse problem which consists in prescribing the final data: in particular we give sufficient conditions for existence and uniqueness. We also provide a probabilistic representation of those PDEs in the form of a solution of a McKean type equation corresponding to the time-reversal dynamics of a diffusion process. The research is motivated by some application consisting in representing some semilinear PDEs (typically Hamilton-Jacobi-Bellman in stochastic control) fully backwardly. This work is based on a collaboration with L. Izydorczyk (ENSTA), N. Oudhane (EDF), G. Tessitore (Milano Bicocca) Best regards, The organizers (Tiziano De Angelis, Giuseppe D'Onofrio, Elena Issoglio)

Large N limits of Wilson loops in gauge theories
by Enrico Scalas 27 Sep '21

27 Sep '21

Care colleghe e colleghi, Vi puo' forse interessare questo seminario che si terra' giovedi' prossimo. Cordiali saluti, Enrico Scalas -- Dear all, This Thursday we kick off our Mathematical Physics seminar series for the new academic year with a talk by Antoine Dahlqvist (Sussex) on Large N limits of Wilson loops in gauge theories Abstract: Gauge theories are a type of field theory introduced and studied from the 70’s by physicists as a theoretical model describing the fundamental interactions between elementary particles. It quickly appeared to be a place where geometry and physics met and influenced each others. In this talk, I shall discuss some questions closer to probability and random matrix theory, inspired by the so-called large N limit regime of Euclidean field theories. I will present some old and new theorems about the Yang-Mills measure for two dimensional space-time geometries. The seminars are fortnightly on Thursdays 12:00 - 13:00 in 5C11 and can also be followed on Zoom https://universityofsussex.zoom.us/j/98075042563?pwd=VTBxSHVMVUl2Y0piblp4Y0… Passcode: 938719 The seminars are open for everyone with an interest in topics on the intersection of Mathematics and Physics The schedule for the seminars this term can be found at https://www.maths.sussex.ac.uk/seminars/mathphys.html To receive further announcements for our seminar series, please sign up to the mailing list 'mathphy_seminar' following the guidance at https://support.microsoft.com/en-us/office/distribution-groups-e8ba58a8-fab… Best wishes, Antoine, Michael, Xavier and Folkert

Diaconis and L. Miclo on "THE random graph" Dear probabilists, We are pleased to inform you that the OWPS will resume on October 7th, from 14:00 to 15:45 UTC. Persi Diaconis and Laurent Miclo will talk about THE random graph and random walk on it. Titles, abstracts and the Zoom link are below the signature, and can be found on the website https://www.owprobability.org/one-world-probability-seminar. We also inform you that, in accordance with the wishes expressed in the pooling, sessions will take place every other week (i.e. ~2 per month). Each session will consist of two talks of 45 minutes each. These two talks will be thematically unified. Please feel free to circulate this email. Probabilistically yours, Bastien Mallein and Sébastien Martineau -------- Persi Diaconis -- Probability theory for THE random graph Pick two Erdös-Renyi (n,1/2) graphs uniformly at random. What's the chance they are the same (isomorphic)? Small. How small? Well, at most n!/ 2^(n choose 2). When n= 100, that's less than 10^-1300. OK, now let n=infinity. The chance that the two graphs are isomorphic is one (!). This is THE random graph (the Rado graph R). I will review its many non-random models and many strange properties. ? It is a natural limit of the set of all finite graphs (a first order property is true for almost all finite graphs if and only if it holds with probability one in R) and this discontinuity is surprising. In joint work with with Sourav Chatterjee we tried to find finite manifestations: For finite n, the largest isomorphic induced subgraph of a pair has size 4log (n) -2loglog(n)-2log(4/e) +1 (within 1, all logs base 2 in probability when n is large). This matches data amazingly well (e.g. for n more than 30) and illuminates problems in constraint satisfaction. Laurent Mico -- A random walk on THE random graph R Let q(j) be a probability on N={0,1,2,...}. Let R be a model of THE random graph. A Markov chain on N starts at i and moves to one of its neighbor j in R with probability proportional to q(j). This Markov chain has a stationary distribution and we inquire about rates of convergence. Since each vertex is connected to half of the others and the diameter of R is 2, it seems likely that convergence is fast. In some models we show that log* (i) steps are necessary and sufficient for convergence. The proof uses a novel variant of Hardy's inequalities for trees. This is joint work with Sourav Chatterjee and Persi Diaconis.
