The long-time dynamics of a system with separated time-scales is best described by a set of metastable states and transitions in between. These dynamical structures are of great importance and their computation tricky, as one does not want to simulate complex systems for a long time. I will consider the Langevin dynamics of such a system and show how the metastable states are encoded in the Fokker-Planck equation whereas the transition between them can be read in a generalized Fokker-Planck equation, which contains all the topological informations relevant for the dynamics.
This is a roughly weekly series of didactical blackboard talks focussing on some theoretical aspect of Condensed Matter, Biological, and Statistical Physics..
