Four subdifferentials are defined for set-valued optimization maps. Some existence theorems and relations among these subdifferentials are obtained. By using them, necessary and sufficient optimality conditions are presented for set-valued optimization problems with respect to -order relation.eninfo:eu-repo/semantics/closedAccessSet-valued optimizationsubdifferentialexistence theoremoptimality conditionArticle10.1080/02331934.2020.17282702-s2.0-850797133246303Q161370WOS:000514723100001Q1
