Abstract

We study the limit behavior of differential equations with non-Lipschitz coefficients that are perturbed by a small self-similar noise. It is proved that the limiting process is equal to the maximal solution or minimal solution with certain probabilities p+p_+ and p=1p+p_-=1-p_+, respectively. We propose a space-time transformation that reduces the investigation of the original problem to the study of the exact growth rate of a solution to a certain SDE with self-similar noise. This problem is interesting in itself. Moreover, the probabilities p+p_+ and pp_- coincide with probabilities that the solution of the transformed equation converges to ++\infty or -\infty as t,t\to\infty, respectively.
