Title: On large-time behavior for birth-spread type nonlinear PDEs

Abstract:
In this talk, we introduce birth-spread type nonlinear partial differential equations which is motivated by a crystal growth phenomenon. Mathematically, an interesting nonlinear phenomenon in terms of asymptotic speed of solutions appears which is sensitive to the shapes of source terms. We discuss properties of large-time asymptotic speed, and also present recent results of large-time asymptotic profile of solutions.
This is a joint work with Y. Giga (Univ. of Tokyo) and H. V. Tran (Univ. of Wisconsin-Madison).

Title: Exponential convergence and hyperbolicity of the minimisers for random Lagrangian systems

Abstract:
We consider the stochastic Burgers equation from the Lagrangian point of view (long-time behaviour of the minimisers) as well as from the point of view of the statistical behaviour of the solutions (long-time convergence towards the stationary measure). In both cases there is a phenomenon of exponential convergence.
