Metastable Transitions in Dynamical Systems with both Time-varying Perturbations and Degenerate Noise
Hanru Zou, Hongjun Gao, Pingyuan Wei +1
This paper investigates the persistence of maximum likelihood paths in degenerate stochastic differential systems and quantifies how small periodic perturbations modulate the metas…

Onsager--Machlup functionals for McKean--Vlasov SDEs via Euler-type approximation
Ying Chao, Pingyuan Wei
The Onsager--Machlup action functional provides a variational framework for characterizing the most probable transition paths of stochastic systems and plays an important role in t…
