“…More recently, Γ-convergence of Onsager-Machlup action functional [12,27], the bounds for the most probable transition time when time is not fixed [23] and the connection between OM action functional and information projection problem [39] are also considered. On the other hand, in specific application, climate change for global warming [49], single-species with Allee effect [44], genetic regulatory network [21] and so on. OM action functional has become an important tool for understanding the dynamics of system.…”
