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

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.

Common best proximity point theorems for certain types of mappings [PDF]

open access: yesMathematica Bohemica
Let $S$ and $T$ be two single-valued non-self-mappings from a nonempty set $\mathcal{P}$ to another nonempty set $\mathcal{Q}$. As they are non-self-mappings, the equations $Sx=x$ and $Tx=x$ do not have a common solution. In other words, they do not have

Best proximity point theorems for cyclic p-contractions with some consequences and applications [PDF]

open access: yesNonlinear Analysis, 2021
In this paper, we introduce the concept of cyclic p-contraction pair for single-valued mappings. Then we present some best proximity point results for such mappings defined on proximally complete pair of subsets of a metric space.

Best proximity pair theorems

open access: yes, 2001
Let \(X\) and \(Y\) be any two topological spaces. A multifunction \(T:X\to 2^Y\) is said to be (i) upper semi-continuous if \(T^{-1}(B)= \{x\in X:(Tx)\cap B\neq\emptyset\}\) is closed in \(X\) whenever \(B\) is a closed subset of \(Y\); (ii) Kakutani multifunction if (a) \(T\) is upper semi-continuous, (b) either \(Tx\) is a singleton for each \(x\in ...

Best Proximity Point Theorems for a Berinde MT-Cyclic Contraction on a Semisharp Proximal Pair [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2018
In this paper, a new type of non-self-mapping, called Berinde MT-cyclic contractions, is introduced and studied. Best proximity point theorems for this type of mappings in a metric space are presented. Some examples illustrating our main results are also

Common best proximity point theorem for multivalued mappings in partially ordered metric spaces

open access: yesFixed Point Theory and Applications, 2017
In this paper, we prove the existence of a common best proximity point for a pair of multivalued non-self mappings in partially ordered metric spaces. Also, we provide some interesting examples to illustrate our main results.

Existence and Convergence of Best Proximity Points for Semi Cyclic Contraction Pairs [PDF]

open access: yesInternational Journal of Analysis and Applications, 2014
In this article, we introduce the notion of a semi cyclic ϕ-contraction pair of mappings, which contains semi cyclic contraction pairs as a subclass.
