Title: Controllability of neutral stochastic integro-differential systems with impulsive effects Author: Abbes Benchaabane (8 May 1945 Univ., Guelma, Algeria) Abstract: This article concerns the complete controllability for nonlinear neutral impulsive stochastic integro-differential system in finite dimensional spaces. Sufficient conditions ensuring the complete controllability are formulated and proved under the natural assumption that the associated linear control system is completely controllable. The results are obtained by using the Banach fixed point theorem. A numerical example is provided to illustrate our technique. Submitted June 15, 2014. Published October 02, 2015.
