Abstract
Exact time-dependent solutions representing generalized one-dimensional Orn stein-Uhlenbeck processes are derived from nonlinear Fokker-Planck equation s and the corresponding diffusion processes are studied. The corresponding systems are related to the Renyi entropy and entropies proposed by Sharma a nd Mittal. In the former case normal diffusion is found with a diffusion la te depending on the order of the Renyi entropy. In the latter case we find anomalous diffusion processes.
