The Pincherle derivative is a concept from the field of functional analysis, particularly in the study of linear operators and spaces of functions. It is a type of derivative that generalizes the traditional notion of differentiation for certain classes of functions, especially those that can be represented as power series or polynomials in some functional spaces.
