Approximate controllability for a new class of stochastic functional differential inclusions with infinite delay

Abstract This manuscript investigates the approximate controllability for a wide range of infinite-delayed semilinear stochastic differential inclusions. First, we construct the expression for a mild solution in terms of the fundamental solution. Then, employing the fixed point theorem for multivalued maps, we formulate a set of sufficient conditions to assure the existence of a solution for the aforementioned system. Further, the approximate controllability for the semilinear stochastic differential inclusion is investigated under the condition that the associated linear deterministic control system is approximately controllable. The discussed results are more general and a continuation of the ongoing research on this issue. Finally, an example is included to highlight the applicability of the considered results.
