Abstract
The Fokker-Planck equation with diffusion coefficient quadratic in space variab- le, linear drift coefficient, and nonlocal nonlinearity term is considered in the framework of a model of analysis of asset returns at financial markets. For special cases of such a Fokker- Planck equation we describe a construction of exact solution of the Cauchy problem. In the general case, we construct the leading term of the Cauchy problem solution asymptotic in a formal small parameter in semiclassical approximation following the complex WKB- Maslov method in the class of trajectory concentrated functions.
