  Noise or fluctuations play an important role in the modeling and
understanding of the behavior of various complex systems in nature.
Fokker-Planck equations are powerful mathematical tool to study behavior of
such systems subjected to fluctuations. In this paper we establish local
well-posedness result of a new nonlinear Fokker-Planck equation. Such equations
appear in the modeling of the grain boundary dynamics during microstructure
evolution in the polycrystalline materials and obey special energy laws.
