Noise-driven transition to quasi-deterministic limit cycle dynamics in excitable systems
Cyrill B. Muratov, Eric Vanden-Eijnden, Weinan E
The effect of small-amplitude noise on excitable systems with large time-scale separation is analyzed. It is found that small random perturbations of the fast excitatory variable r…

The Heterogeneous Multi-Scale Method
Weinan E, Bjorn Engquist
The heterogeneous multi-scale method (HMM) is a general strategy for dealing with problems involving multi-scales, with multi-physics, using multi-grids. It not only unifies severa…
