Multiscale Gentlest Ascent Dynamics for Saddle Point in Effective Dynamics of Slow-Fast System
Shuting Gu, Xiang Zhou
Here we present a multiscale method to calculate the saddle point associated with the effective dynamics arising from a stochastic system which couples slow deterministic drift and…

The Gentlest Ascent Dynamics
Weinan E, Xiang Zhou
Dynamical systems that describe the escape from the basins of attraction of stable invariant sets are presented and analyzed. It is shown that the stable fixed points of such dynam…
