In mathematics, the Pincherle derivative[1] of a linear operator on the vector space of polynomials in the variable x over a field is the commutator of with the multiplication by x in the algebra of endomorphisms . That is, is another linear operator
(for the origin of the notation, see the article on the adjoint representation) so that
This concept is named after the Italian mathematician Salvatore Pincherle (1853–1936).
