Controllability results for impulsive differential systems with finite delay

This paper establishes some su cient conditions for controllability of impulsive functional di erential equa- tions with nite delay in a Banach space. The results are obtained by using the measures of noncompactness and Monch xed point theorem. Particularly, we do not assume the compactness of the evolution system. Finally, an example is provided to illustrate the theory.
