Best Proximity Pair Results for Relatively Nonexpansive Mappings in Geodesic Spaces [PDF]

open access: yesNumerical Functional Analysis and Optimization, 2014
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 $x \in A \cup B$ such that $d(x,Tx)=\text{dist}(A,B)$.

Best Proximity Pairs in Ultrametric Spaces [PDF]

open access: yesP-Adic Numbers, Ultrametric Analysis, and Applications, 2021
In the present paper, we study the existence of best proximity pairs in ultrametric spaces. We show, under suitable assumptions, that the proximinal pair $(A,B)$ has a best proximity pair. As a consequence we generalize a well known best approximation result and we derive some fixed point theorems.
