First, we prove the existence of mild solution of the semilinear backward stochastic evolution inclusion systems using a multivalued fixed point theorem. Then, we obtain the approximate controllability result for semilinear backward stochastic evolution inclusion systems through the linear systems corresponding to these semilinear backward stochastic evolution inclusion systems under appropriate conditions. In particular, our study extends the results of the concept of approximate controllability to backward stochastic evolution inclusion systems.eninfo:eu-repo/semantics/openAccessBackward Stochastic Evolution InclusionsApproximate ControllabilityMild SolutionsMultivalued MapsHausdorff Measure Of NoncompactnessArticle543Q3Q3834844WOS:001519198000004
