Detailed program: 4:00 pm (sharp): introductory talk for PhD students and postdocs by Bastián Mora 4:30 pm: coffee and tea will be served in the Cluster Lounge 5:00 pm (sharp): Colloquium-talk by Prof. Dr. Alejandro Ramirez Abstract: The KPZ universality describes fluctuations of a one dimensional interface separating a stable phase from an unstable one. This kind of behavior has been proven only for a few mathematical models, most of them "directed", meaning that paths visit points at most once. Weak KPZ universality, refers to a rescaling towards the 1+1 stochastic heat equation, for which KPZ universality is expected. We describe one of the few instances where weak KPZ universality has been established for a non-directed model: the planar stochastic heat equation with spatial white noise, corresponding to a Skorokhod interpretation of integrals. This talk is based on a joint work with Jeremy Quastel and Balint Virag.
