| Abstract: | The general Fokker Planck equation of a system driven by correlated noises is used to study a single bistable kinetic process driven by correlated additive and multiplicative Gaussian white noises. The stationary probability distribution (SPD) is obtained. Comparisons are made between systems driven by positive correlated noises and those driven by negative correlated noises in the change of SPD and the position of the extreme value. The effects of various parameters on the transition between unimodal SPD and bimodal SPD are studied. |
