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

open access: greenNumerical 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 ...

Approximate Best Proximity Pairs in Metric Space [PDF]

open access: goldAbstract 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.

Best Proximity Pairs Theorems for Continuous Set-Valued Maps [PDF]

open access: goldFixed Point Theory and Applications, 2008
A best proximity pair for a set-valued map F:A⊸B with respect to a set-valued map G:A⊸A is defined, and a new existence theorem of best proximity pairs for continuous set-valued maps is proved in nonexpansive retract metric spaces.

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

open access: goldAbstract 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 ...

Convergence and Best Proximity Points for Generalized Contraction Pairs [PDF]

open access: goldMathematics, 2019
This paper is devoted to studying the existence of best proximity points and convergence for a class of generalized contraction pairs by using the concept of proximally-complete pairs and proximally-complete semi-sharp proximinal pairs.

Some results on best proximity pair theorems

open access: diamondApplied General Topology, 2002
Best proximity pair theorems are considered to expound the sufficient conditions that ensure the existence of an element xo ϵ A, such that d(xo; T xo) = d(A;B) where T : A  2B is a multifunction defined on suitable subsets A and B of a normed linear ...

Best proximity pair theorems for relatively nonexpansive mappings

open access: diamondApplied 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

Noncyclic Meir-Keeler contractions and best proximity pair theorems

open access: goldDemonstratio 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.
