Abstract

In this paper, we first recall some recent results on polar-analytic functions. Then we establish Mellin analogues of a classical interpolation of Valiron and of a derivative sampling formula. As consequences a new differentiation formula and an identity theorem in Mellin--Bernstein spaces are obtained. The main tool in the proofs is a residue theorem for polar-analytic functions.
