Best proximity and best periodic points for proximal nonunique contractions
Sahin, Hakan; Aslantas, Mustafa; Altun, Ishak (Springer Basel Ag, 2021)Taking into account nonunique fixed point and periodic point results of Ciric (Institut Mathematique 17, 52-58, 1974) and best proximity point results in the literature, we introduce the concept of proximal nonunique ... -
Best proximity point theorems for cyclic p-contractions with some consequences and applications
Aslantas, Mustafa; Sahin, Hakan; Altun, Ishak (Vilnius Univ, Inst Mathematics & Informatics, 2021)In this paper, we introduce the concept of cyclic p-contraction pair for single-valued mappings. Then we present some best proximity point results for such mappings defined on proximally complete pair of subsets of a metric ... -
Ciric type cyclic contractions and their best cyclic periodic points
Aslantas, Mustafa; Sahin, Hakan; Altun, Ishak (North Univ Baia Mare, 2022)In the present paper, by introducing a new notion named as nonunique cyclic contractions, we give some best proximity point results for such mappings. Then, we indicate the shortcoming of the concept of best periodic ... -
KW-Type Nonlinear Contractions and Their Best Proximity Points
Altun, Ishak; Aslantas, Mustafa; Sahin, Hakan (Taylor & Francis Inc, 2021)In this paper, we present two main results about best proximity points for multivalued mappings. First, taking into account Klim and Wardowski's approach in fixed-point theory, we obtain a new result for multivalued mappings ... -
A new approach to fractals via best proximity point
Altun, Ishak; Sahin, Hakan; Aslantas, Mustafa (Pergamon-Elsevier Science Ltd, 2021)In this paper, we present a new approach to fractals through best proximity points, inspired by the remarkable relationship between fixed point theory and fractal theory. In this way, we introduce the concept of proximal ...
