Fixed point and coincidence point theorems
Tamkang Journal of Mathematics, 2012 In this paper, we present a generalization of some fixed point and coincidence point theorems using the notion of a on a complete metric space.Consequently, we improve and generalize various results existing in the literature.

Partial S-metric spaces and coincidence points
Filomat, 2019 In this paper, the concept partial S-metric space is introduced as a generalization of S-metric space. We prove certain coincidence point theorems in partial S-metric spaces. The results we obtain generalize many known results in fixed point theory. Also, some examples show the e_ectiveness of this approach.

Coupled Coincidence and Common Fixed Point Theorems for Set-valued and Single-valued Mappings in fuzzy Metric Space [PDF]
, 2012 In this paper, we define the tangential property and the generalized coincidence property for a pair of set-valued and single-valued mappings and use it to prove some coupled coincidence and common fixed point theorems for a hybrid pair of mappings ...

Relational Meir-Keeler Contractions and Common Fixed Point Theorems
Journal of Function Spaces, 2022 In this article, we prove some coincidence and common fixed point theorems under the relation-theoretic Meir-Keeler contractions in a metric space endowed with a locally finitely T-transitive binary relation.

Substitution Delone Sets with Pure Point Spectrum are Inter Model Sets
, 2009 The paper establishes an equivalence between pure point diffraction and certain types of model sets, called inter model sets, in the context of substitution point sets and substitution tilings.

Localized intersection of currents and the Lefschetz coincidence point theorem
, 2015 We introduce the notion of a Thom class of a current and define the localized intersection of currents. In particular we consider the situation where we have a smooth map of manifolds and study localized intersections of the source manifold and currents ...

Coincidence Points in Generalized Metric Spaces
Set-Valued and Variational Analysis, 2014 The authors continue the research (see [\textit{A. V. Arutyunov}, Dokl. Math. 76, No. 2, 665--668 (2007; Zbl 1152.54351); translation from Dokl. Akad. Nauk, Ross. Akad. Nauk 416, No. 2, 151--155 (2007)]) on coincidence points for maps (single-valued and set-valued) such that one of them is \(\beta\)-Lipschitz continuous and the second one is an ...
