It is well-known that diffusions with gradient drifts exhibit metastable behavior. The large deviation estimates of Wentzel-Freidlin and classical Eyring-Kramers Formula give a precise description for such metastable behavior. For non-gradient models, the large-deviation techniques are still applicable, though no rigorous analog of Eyring-Kramers Formula is available. In this talk I give an overview of the existing results and conjectures for general metastable diffusions.
