Abstract

In this paper, we investigate global uniqueness results for fractional functional differential equations with infinite delay in Frechet spaces. We shall rely on a nonlinear alternative of Leray-Schauder type in Frechet spaces due to Frigon and Granas. The results are obtained by using the @a-resolvent family (S"@a(t))"t"="0 on a complex Banach space X combined with the above-mentioned fixed point theorem. As an application, a controllability result with one parameter is also provided to illustrate the theory.
