New fixed-circle results on s-metric spaces
Özgür, Nihal Yılmaz; Taş, Nihal; Çelik, Ufuk (Int Center Scientific Research & Studies, 2017)In this paper our aim is to study some fixed-circle theorems on 5 metric spaces. For this purpose we give new examples of S-metric spaces and investigate some relationships between circles on metric and S-metric spaces. ... -
A new solution to the discontinuity problem on metric spaces
Çelik, Ufuk; Özgür, Nihal Yılmaz (Scientific Technical Research Council Turkey-Tubitak, 2020)We study on the Rhoades' question concerning the discontinuity problem at fixed point for a self-mapping T of a metric space. We obtain a new solution to this question. Our result generalizes some recent theorems existing ... -

Çelik, Ufuk (Balıkesir Üniversitesi Fen Bilimleri Enstitüsü, 2021)Sabit nokta teorisinde daralma şartlarının çeşitli genellemelerinin ortaya çıkardığı ilgi çekici bazı geometrik yapılar mevcuttur. Bu çalışmanın amacı, dönüşümlerin sabit noktası birden fazla olduğunda sabit nokta kümesinin ... -
Wardowski type contractions and the fixed-circle problem on s-metric spaces
Mlaiki, Nabil; Çelik, Ufuk; Taş, Nihal; Özgür, Nihal Yılmaz; Mukheimer, Aiman (Hindawi Ltd, 2018)In this paper, we present new fixed-circle theorems for self-mappings on an S-metric space using some Wardowski type contractions, psi-contractive, and weakly psi-contractive self-mappings. The common property in all of ...
