Giovedì 7 dicembre, nell'aula Cantimori della Scuola Normale Superiore
(Palazzo D'Ancona), si terranno i seguenti seminari:
14:00 Milton Jara (IMPA)
Title: Entropy methods in interacting particle systems.
15:00 Massimiliano Gubinelli (Bonn)
Title: Weak universality of singular SPDEs.
Seguono gli abstract. Tutti gli interessati sono invitati a partecipare.
Abstract M. Jara: We develop a variational formula to estimate the
moment generating function of additive functionals of Markov processes.
Combined with a related variational formula for the evolution of the
relative entropy of the law of the process with respect to suitable
reference measures, this variational formula serves as a substitute for
the martingale method pioneered by Kipnis-Varadhan in the case of
out-of-equilibrium interacting particle systems.
Abstract M. Gubinelli: I will discuss the problem of controlling the
large scale limit of weakly non-linear SPDEs in the regime where the
non-linearity survives at the macroscopic scale giving rise to singular
non-linear SPDEs.
