Miercoles 7 de Octubre

14.15 hrs.
SPEAKER: Julio Rossi, U. de Buenos Aires

TITULO: Tug-of-War games and PDEs

ABSTRACT: In this talk we will discuss some recent results
that relate value functions of Tug-of-War games (as
introduced by Peres-Schram-Sheffield-Wilson).
In particular we show how this games could be used to
obtain solutions to the p-laplacian and,
inspired by this approach, we provide an asymptotic
mean formula for p-harmonic functions.


15.15 hrs.
SPEAKER: Mauricio Sepulveda. U. de Concepcion

TITULO: Uniform stabilization for the critical generalized Korteweg-de
Vries equation.

RESUMEN: We analyse the convergence of a fully-implicit numerical
scheme for the critical generalized KdV equation (KdV-4 or GKdV with
$p=4$) in a bounded domain with a localized damping term. The damping is
supported in a subset of the domain, so that the solutions of the
continuous model issuing from small data are globally defined and
exponentially decreasing in the energy space. Combining discrete
multipliers and compactness arguments we show that the smallness of the
initial condition leads to the uniform (with respect to the mesh size)
exponential decay of the energy associated to the scheme.
