Pincherle derivative

The Pincherle derivative is an example of a derivation in abstract algebra.

The Pincherle derivative is named after him.

Also see Pincherle derivative.

In other words, the shift operators are eigenvectors of the Pincherle derivative, whose spectrum is the whole space of scalars .

Weisstein, Eric W. "Pincherle Derivative".

Naturally occurring examples of derivations are partial derivatives, Lie derivatives, the Pincherle derivative, and the commutator with respect to an element of the algebra.
