»Phase transitions in stochastic partial differential equations with rough and correlated noise«

Abstract:
We analyze the qualitative behavior of stochastic partial differential equations (SPDEs) with a particular focus on phase transitions. To this aim we investigate a change of sign in the finite-time Lyapunov exponents (FTLEs) of the SPDE in a small noise regime and close to a phase transition. Under suitable assumptions, the FTLEs are positive and thus indicate a change of stability. These results are applied to the stochastic Allen-Cahn and Burgers equation with non-Markovian noise and to singular SPDEs. Moreover, we also discuss properties of FTLEs, in particular large deviations type results. This talk is based on joint works with Dirk Blömker, Nicolas Perkowski and Chara Zhu.
