Past talks

We consider Fokker-Planck equations in several dimensions with general nonconvex potentials that have multiple local minima. In the one-dimensional case, the vanishing diffusion limit is governed by the so called "Kramers' law", which yields simple and expicit reaction-diffusion dynamics. In the talk, we extend this to the higher dimensional setting and describe a graph structure for the limit system. There, the limit dynamics are much more sensitive to the geometry of the potential, which can change the topology of the underlying graph.
