On well-posedness of an initial value problem for nonlinear second-order impulsive integro-differential equations of Volterra type in Banach spaces

In this paper, we develop an existence and uniqueness theorem of the solution to an initial value problems for a class of second-order impulsive integro-differential equations of Volterra type in a real Banach space by using the generalized Banach fixed point theorem. An explicit iterative scheme for the solution and an error estimate of the approximation sequence for the initial value problem are also derived. Two examples are presented to demonstrate the application of our results. © 2006 Elsevier Inc. All rights reserved
