Abstract :
Semiclassical methods have shown to be very efficient to get quantitative description of metastability of Langevin dynamics. In this talk we try to explain the main ideas of this approach in both reversible and non-reversible cases.
Keywords : eigenvalue splitting; Kramers-Fokker-Planck operator; Fokker-Planck equation; Kramers equation; Witten Laplacian; semiclassical limit; Langevin dynamics
