Best proximity pair theorems for relatively nonexpansive mappings

open access: yesApplied General Topology, 2009
Let A, B be nonempty closed bounded convex subsets of a uniformly convex Banach space and T : A∪B → A∪B be a map such that T(A) ⊆ B, T(B) ⊆ A and ǁTx − Tyǁ ≤ ǁx − yǁ, for x in A and y in B. The fixed point equation Tx = x does not possess a solution when

Some Results on the Best Proximity Pair [PDF]

open access: yesAbstract and Applied Analysis, 2011
We give some new conditions for existence and uniqueness of best proximity point. We also introduce the concept of strongly proximity pair and give some interesting results.

Noncyclic Meir-Keeler contractions and best proximity pair theorems

open access: yesDemonstratio Mathematica, 2018
In this article, we consider the class of noncyclic Meir-Keeler contractions and study the existence and convergence of best proximity pairs for such mappings in the setting of complete CAT(0) spaces.

Best proximity pair and fixed point results for noncyclic mappings in modular spaces

open access: yesArab Journal of Mathematical Sciences, 2018
In this paper, we formulate best proximity pair theorems for noncyclic relatively ρ-nonexpansive mappings in modular spaces in the setting of proximal ρ-admissible sets.

Best proximity pair results for relatively nonexpansive mappings in geodesic spaces [PDF]

open access: yesNumerical Functional Analysis and Optimization, 2013
Given $A$ and $B$ two nonempty subsets in a metric space, a mapping $T : A \cup B \rightarrow A \cup B$ is relatively nonexpansive if $d(Tx,Ty) \leq d(x,y) \text{for every} x\in A, y\in B.$ A best proximity point for such a mapping is a point $x \in A ...

Best Proximity Pair Theorems for Multifunctions with Open Fibres

open access: yesJournal of Approximation Theory, 2000
Let \(A\) and \(B\) be non-empty subsets of a normed linear space \(E\), and let \(T:A\to 2^B\) be a convex multi-valued function with open fibres \(T^{-1}(y)\) (i.e.) \(\{x\in X:y\in Tx\}\). For an element \(x_0\in A\) sufficient conditions are found so that \(\text{dist}(x_0, Tx_0)= \text{dist}(A,B)\).

On a generalization of a relatively nonexpansive mapping and best proximity pair

open access: yesFixed Point Theory and Algorithms for Sciences and Engineering, 2023
Let A and B be two nonempty subsets of a normed space X, and let T : A ∪ B → A ∪ B $T: A \cup B \to A \cup B$ be a cyclic (resp., noncyclic) mapping.

Approximate Best Proximity Pairs in Metric Space [PDF]

open access: yesAbstract and Applied Analysis, 2011
Let A and B be nonempty subsets of a metric space X and also T:A∪B→A∪B and T(A)⊆B, T(B)⊆A. We are going to consider element x∈A such that d(x,Tx)≤d(A,B)+ϵ for some ϵ>0. We call pair (A,B) an approximate best proximity pair.

Common best proximity points for a pair of mappings with certain dominating property

open access: yesDemonstratio Mathematica, 2023
This article introduces a type of dominating property, partially inherited from L. Chen’s, and proves an existence and uniqueness theorem concerning common best proximity points.
