Existence results for second-order impulsive neutral functional differential equations with nonlocal conditions

Abstract

The existence of mild solutions for second-order impulsive semilinear neutral functional differential equations with nonlocal conditions in Banach spaces is investigated. The results are obtained by using fractional power of operators and Sadovskii's fixed point theorem.
