Abstract. We propose a method to determine a special class of
discrete symmetries  which we call quantized  of differential
equations, based on solution of a linear functional equation. By the
same method, we can determine differential equations possessing a
given quantized symmetry by solving a linear (standard, i.e. non
functional) PDE. Geometrical motivation and interpretation are also
given, together with simple but physically significant examples.
