DOI: 10.3390/axioms11100573
Abstract: In this manuscript, we defined contractions in the context of double-controlled metric spaces and partially ordered double-controlled metric spaces. We established new fixed-point results and defined the notion of double-controlled metric space on a Reich-type… read more here.
