Best Proximity Point Theorems for Cyclic Relatively ρ-Nonexpansive Mappings in Modular Spaces

open access: yesAbstract and Applied Analysis, 2018
In this paper we introduce the notion of proximal ρ-normal structure of pair of ρ-admissible sets in modular spaces. We prove some results of best proximity points in this setting without recourse to Zorn’s lemma.

On best proximity pair theorems and fixed-point theorems [PDF]

open access: yesAbstract and Applied Analysis, 2003
The significance of fixed‐point theory stems from the fact that it furnishes a unified approach and constitutes an important tool in solving equations which are not necessarily linear. On the other hand, if the fixed‐point equation Tx = x does not possess a solution, it is contemplated to resolve a problem of finding an element x such that x is in ...

Common Best Proximity Points for Cyclic φ-Contraction Maps [PDF]

open access: yesInternational Journal of Analysis and Applications, 2016
The purpose of this paper is to introduce new types of contraction condition for a pair of maps $(S,T)$ in metric spaces. We give convergence and existence results of best proximity points of such maps in the setting of uniformly convex Banach spaces ...

Bipartite graphs and best proximity pairs

open access: yesUkrainian Mathematical Bulletin, 2022
We say that a bipartite graph $G(A, B)$ with fixed parts $A$, $B$ is proximinal if there is a semimetric space $(X, d)$ such that $A$ and $B$ are disjoint proximinal subsets of $X$ and all edges $\{a, b\}$ satisfy the equality $d(a, b) = \operatorname{dist}(A, B)$. It is proved that a bipartite graph $G$ is not isomorphic to any proximinal graph iff $G$

Proximity Point Properties for Admitting Center Maps [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2019
In this work we investigate a class of admitting center maps on a metric space. We state and prove some fixed point and best proximity point theorems for them. We obtain some results and relevant examples.

On a new variant of F-contractive mappings with application to fractional differential equations

open access: yesNonlinear Analysis, 2022
The present article intends to prove the existence of best proximity points (pairs) using the notion of measure of noncompactness. We introduce generalized classes of cyclic (noncyclic) F-contractive operators, and then derive best proximity point (pair)

Best Proximity Pair Theorems for Noncyclic Mappings in Banach and Metric Spaces [PDF]

open access: yes, 2016
Let A and B be two nonempty subsets of a metric space X. A mapping T : A[B ! A[B is said to be noncyclic if T(A) A and T(B) B. For such a mapping, a pair (x; y) 2 A B such that Tx = x, Ty = y and d(x; y) = dist(A;B) is called a best proximity ...
