Abstract
We consider the Langevin equation with multiplicative noise term which depends on
time and space. The corresponding Fokker-Planck equation in Stratonovich approach
is investigated. Its formal solution is obtained for an arbitrary multiplicative noise
term given by \(g(x,t)=D(x)T(t)\), and the behaviors of probability distributions, for
some specific functions of \(D(x)\)% , are analyzed. In particular, for \(D(x)\sim |
x| ^{-\theta /2}\), the physical solutions for the probability distribution in the
Ito, Stratonovich and postpoint discretization approaches can be obtained and analyzed.
