## Abstract

New fixed point results are presented for admissible pairs and maps (admissible in the sense of Gorniewicz) defined on subsets of a Frechet space E. The proof relies on the notion of a pseudo open set, degree theory, and on viewing E as the projective limit of a sequence of Banach spaces.
