In this paper, we generalize and unify Ciric' and Fisher fixed points results for quasi-contractions on metric space to omega-distance on complete metric spaces. We also extend some results of Kada, Suzuki and Takahashi, and Suzuki. Our methods of proofs are new and even simpler than the corresponding methods in metric spaces.eninfo:eu-repo/semantics/closedAccessomega-distancefixed pointquasi-contractionArticleQ3Q2421114WOS:000457870000001
