摘要：

The authors obtain a complete classification of the possible types of the extended symmetry of any Fokker-Planck equation, together with a necessary and sufficient condition for each type. They give also the most general form (up to a change of variables) of the Lie generators of these symmetries, and a comparison with the case of the heat equation.
