Asymmetric space-dependent systems: partial stabilization through the addition of noise and exact solutions for the corresponding nonlinear Langevin equations
KS Fa, CL Ho, YB Matos, MGE da Luz - Physica Scripta, 2023 - iopscience.iop.org
In many instances, the dynamical richness and complexity observed in natural phenomena
can be related to stochastic drives influencing their temporal evolution. For example, random …
