As an application that illustrates the abstract results a nonlocal impulsive quasilinear multi-delay integro-partial differential system of fractional order is given.

We assume that -A t . is a closed linear operator defined on a dense domain D A in X into X such that D A is independent of t. It is assumed also that -A t . generates an evolution operator in the Banach space X. The functions f J Xr 1 X g A X Xk 1 X h PC J X X u b u b1 . u br u Ỳ 1 . u k and bp gq J J are given where p 1 2 . r and q 1 2 . k. Here J 0 a and A t s . 0 s t a . Let PC J X consist of functions u from J into X such that u t is continuous at t ti and left continuous at t ti and the right limit u t exists for i 1 2 . m. Clearly PC J X is a Banach space with the norm u PC supteJ u t and let Xu ti u t u t constitutes an impulsive condition. Fractional differential .
