correlation between the two Wiener processes, which model the two white noise sources. This model can be useful to describe the … noise on the statistical properties of the escape time with reference to the noise enhanced stability (NES) phenomenon, that … is the noise induced enhancement of the lifetime of a metastable state. We observe NES effect in our model with …

multiplicative noise is analyzed. We find the role of the external noise on the long time probability distribution of the ith density …

-reversible noise is analyzed. The calculation of the effective diffusion coefficient is reduced to the mean first passage time problem … supersymmetric potential modulated by: (i) an external white Gaussian noise and (ii) a Markovian dichotomous noise. For both cases … in the absence of thermal noise. For rectangular potential the diffusion slows down, for all parameters of noise and of …

The dynamics of a spatially extended system of two competing species in the presence of two noise sources is studied. A … correlated dichotomous noise acts on the interaction parameter and a multiplicative white noise affects directly the dynamics of … Gaussian approximation. In this formalism the system dynamics is analyzed for different values of the multiplicative noise …
