Trajectory Controllability of Impulsive Neutral Stochastic Functional Integrodifferential Equations Driven by Fbm With Noncompact Semigroup Via Mönch Fixed Point

Abstract

The aim of this work is to study the mild solutions for a class of impulsive neutral stochastic functional integrodifferential equations driven by fractional Brownian motion using noncompact semigroup in a Hilbert space. We assume that the linear part has a resolvent operator not necessarily compact but the operator norm is continuous. Sufficient conditions for the existence of mild solutions are obtained using the Hausdorff measure of noncompactness and the Monch fixed point theorem. Furthermore, under some suitable assumptions, the considered system's trajectory (T-) controllability is established using generalized Gronwall's inequality. An example is delivered to illustrate the obtained theoretical results. Finally, real life fermentation example is discussed to supporting the proposed system.
