Abstract
The authors study symmetry properties of some Fokker-Planck (FP) equations. In the one-dimensional case, when symmetry groups turn out to be six-parameter ones, this allows us to find changes of variables to reduce such FP equations to the one-dimensional heat equation. They present seven well known FP equations which are reduced to the heat equation. They also study the symmetry and obtain some exact solutions of the Kramers equation.
