Integral boundary value problem for impulsive integro-differential equations in Banach spaces.

In this paper, by using the cone theory and monotone iterative technique, we investigate the existence of extremal solutions and unique solution of the integral boundary value problem for a class of first-order impulsive integro-differential equations in a real Banach space. An explicit iterative scheme for the unique solution and an error estimate of the approximation sequence are also derived. [ABSTRACT FROM AUTHOR]
