Persistence and long-time breakdown of most probable paths under time-dependent fractional noise with applications to KAM tori
Yanbin Zhu, Xiaomeng Jiang, Yong Li
We investigate the persistence of most probable paths through the Onsager--Machlup functional for multidimensional stochastic differential equations driven by fractional Brownian m…

Onsager-Machlup Functional for SDE with Time-Varying Fractional Noise
Yanbin Zhu, Xiaomeng Jiang, Yong Li
In this paper, we derive the Onsager-Machlup functional for stochastic differential equations driven by time-varying fractional noise of the form X(t) = x0 + integral from 0 to t b…
