Some fixed point results on Ultrametric Space
Topological Algebra and its Applications, 2022 The present paper deals with new fixed point theorems by means of F−contraction. The results are present in spherically complete ultrametric space for single valued rational type mappings.

Demonstratio Mathematica, 2023 In this article, a definition of a b(αn,βn){b}_{\left({\alpha }_{n},{\beta }_{n})}-best approximations of b(αn,βn){b}_{\left({\alpha }_{n},{\beta }_{n})}-hypermetric spaces over Banach algebras is given. Our objective is to prove the concept of extension

Dold sequences, periodic points, and dynamics
Bulletin of the London Mathematical Society, Volume 53, Issue 5, Page 1263-1298, October 2021., 2021 Abstract In this survey we describe how the so‐called Dold congruence arises in topology, and how it relates to periodic point counting in dynamical systems.

Collectively Fixed Point Theory in the Compact and Coercive Cases
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2022 We present collectively fixed point results for multivalued maps which automatically generate analytic alternatives and minimax inequalities. As an application we consider equilbrium type problems for generalized games.

Remarks on some coupled coincidence point results in partially ordered metric spaces
Arab Journal of Mathematical Sciences, 2014 In this paper we have used a method of reducing coupled coincidence and coupled fixed point results in partially ordered metric spaces to the respective results for mappings with one variable, even obtaining (in some cases) more general theorems.

Coincidence and Common Fixed Point Theorems via ϱ-Class Functions in Elliptic Valued Metric Spaces
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2021 The main goal of this study is to define a new metric space which is a generalization of complex valued metric spaces introduced by Azam et al.

Fixed-Circle Problem on S-Metric Spaces with a Geometric Viewpoint [PDF]
, 2018 Recently, a new geometric approach which is called the fixed-circle problem has been gained to fixed-point theory. The problem is introduced and studied using different techniques on metric spaces.

Some Fixed Point Results for Sehgal-Proinov Type Contractions in Modular b−Metric Spaces
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2023 In this paper, inspired by Proinov type contractions, we intend to acquire novel definitions and results that expand Sehgals [3] metric fixed point theory in the sense of modular b−metric space. To demonstrate the theorems, we employ a general form of (α,

A new class of unsaturated mappings: Ćirić-Reich-Rus contractions
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2022 Using the technique of enriching contractive type mappings, we introduce a more general concept of enriched Ćirić-Reich-Rus contraction than the one studied in [Berinde, V.; Păcurar, M.
