Abstract

A criterion for the differentiability of a function f : X → Y , where X and Y are both Banach spaces, is given. Moreover, this criterion is applied to obtain the usual rules of the differential calculus of an elementary fashion and to obtain the differentiability of some norms of classical functional spaces.
