Seminario di L. Izydorczyk in Bicocca
by Gianmario Tessitore 02 Apr '19

02 Apr '19

Lunedì *8 aprile* alle ore *10:30 *nell'*Aula 6 dell'edificio U3* dell'Università di Milano-Bicocca il Dottor: *Lucas Izydorczyk *(ENSTA-ParisTech, Institut Polytechnique de Paris) terrà un seminario dal titolo: *McKean representation of time reversed diffusions* *Abstract:* It is well-known that, under suitable conditions, the time-reversal of a diffusion process fulfills a stochastic differential equations involving the law marginal densities. The basic idea is here to consider it as the solution of a McKean type problem where the law density unknown. Under natural conditions we show well-posedness for that problem. tutti gli interessati sono invitati ad intervenire -- Gianmario Tessitore Dipartimento di Matematica e Applicazioni Università degli Studi di Milano-Bicocca

********************************************************************* SEMINARI DI PROBABILITÀ E STATISTICA MATEMATICA DIPARTIMENTO DI MATEMATICA "G. PEANO" UNIVERSITÀ DEGLI STUDI DI TORINO ********************************************************************* Giovedì 11 Aprile 2019 alle ore 10:00 in Aula 4 presso il Dipartimento di Matematica "G. Peano" dell'Università degli Studi di Torino, Via Carlo Alberto 10, Il Prof. *Jozsef Lorinczi* (Department of Mathematical Sciences – Loughborough University, UK) terrà un seminario dal titolo *The location of maxima of solutions to some non-local equations* Abstract: I will consider a class of non-local equations, assuming that their solutions have a global maximum, and discuss estimates on their position. Such points are of special interest as they describe where hot-spots settle on the long run or, in a probabilistic description, the region around which paths typically concentrate. I will address, on the one hand, the interplay of competing parameters whose compromise the resulting location is, and the impact of geometric constraints, on the other. This is joint work with A. Biswas, based on the recent papers [1] Universal constraints on the location of extrema of eigenfunctions of non-local Schrödinger operators, J Diff Equations, https://doi.org/10.1016/j.jde.2019.01.007, 2019 [2] Maximum principles and Aleksandrov-Bakelman-Pucci type estimates for non-local Schrödinger equations with exterior conditions, to appear in SIAM J Math Anal, 2019 (arXiv:1711.09267) [3] Maximum principles for time-fractional Cauchy problems with spatially non-local components, Fract Calc Appl Anal 21, 1335–1359, 2018 https://doi.org/10.1515/fca-2018-0070 [4] Ambrosetti-Prodi type results for Dirichlet problems of the fractional Laplacian, arXiv:1803.08540, 2018 [5] Hopf's lemma for viscosity solutions to a class of non-local equations with applications, arXiv:1902.07452, 2019 Tutti gli interessati sono invitati a partecipare. -- Toaldo Bruno Department of Mathematics University of Torino Via Carlo Alberto 10 10123 Torino, Italy tel: +39 0110912850

seminario Paolo Di Tella a Roma
by Anna Vidotto 02 Apr '19

02 Apr '19

Cari tutti, Ricordo il seminario che si terrà venerdì 5 aprile alle ore 16.30 in aula D’Antoni, Dipartimento di Matematica, Università degli Studi di Roma Tor Vergata. Speaker: Paolo Di Tella (Technische Universität Dresden) 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 F is preserved in the progressive enlargement G by a random time τ avoiding F-stopping times and such that F is immersed in G. As an application of this, we can solve an exponential utility maximization problem in the enlarged filtration 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 ∧ τ]. — This talk is part of the activity of the MIUR Excellence Department Project CUP E83C18000100006 — Tutti gli interessati sono invitati a partecipare. Grazie per l’attenzione, Anna Vidotto --------- Anna Vidotto PostDoc Researcher Dipartimento di Matematica Università degli Studi di Roma Tor Vergata https://sites.google.com/view/annavidotto
