Our results are based on a new approach, which is called set-valued theta-contraction and they extend and generalize many fixed point theorems in the literature.eninfo:eu-repo/semantics/closedAccessFixed pointMultivalued mappingsMultivalued theta-contractionComplete metric spaceArticle43138940210.1007/s40840-018-0689-72-s2.0-85076892447Q1WOS:000526822700023Q1
