Mercoledì 25 febbraio 2015 ore 14:30, Pablo Blanc "Tug-of-war games and PDEs"

Mercoledì 25 febbraio 2015 alle ore 14:30, presso la Sala delle Riunioni del Dipartimento (III piano) Pablo Blanc (University of Buenos Aires e CONICET) terrà un seminario di analisi dal titolo:

Tug-of-war games and PDEs


Tutti gli interessati sono invitati a partecipare

Proff. Alessandra Lunardi, Giampiero Palatucci



Tug-of-War is a two-player zero-sum stochastic game. At an initial time, a token is placed on an bounded domain. At each turn a fair coin is tossed to decide which player is allow to move the token an epsilon-step. The game ends when the token hits the boundary, where a given function determines how much Player II must pay to Player I. In this talk we will discuss some versions of this game and how they are related to PDEs as the p-laplacian.

In the first part of the talk, the speaker will introduce the topic for non-experts in the field and he will present "a road map from the game to the PDEs".
