Metastability in non-reversible diffusion processes M. Mariani HSE |

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. Language: English |
