Abstract:
We present two variational formulae for the capacity in the
context of non-selfadjoint elliptic operators. The minimizers of these variational
problems are expressed as solutions of boundary-value elliptic equations.
We use these principles to provide a sharp estimate for the transition
times between two different wells for non-reversible diffusion processes.
This estimate permits to describe the metastable behavior of the system.
This is a joint work with C.Landim and I.Seo.
