  Based on the well-known relation between Fokker-Planck equations and
Schroedinger equations of quantum mechanics (QM), we propose new deformed
Fokker-Planck (FP) equations associated with the Schroedinger equations of
"discrete" QM. The latter is a natural discretization of QM and its
Schroedinger equations are difference instead of differential equations.
Exactly solvable FP equations are obtained corresponding to exactly solvable
"discrete" QM, whose eigenfunctions include various deformations of the
classical orthogonal polynomials.
