DESCRIPTION:Shuo Yan – University Maryland               
       \nSeminar in Mathematics\nWe consider coupled slow-fast stocha
 stic processes\, where the averaged slow motion is given by a two-dimensio
 nal Hamiltonian system with multiple critical points. On a proper time sca
 le\, the evolution of the first integral converges to a diffusion process 
 on the corresponding Reeb graph\, with certain gluing conditions specified
  at the interior vertices. The case of additive perturbations was consider
 ed in the classic work of M. Freidlin and A. Wentzell. The current result
  shares some common features but requires a new set of techniques.\n
