G-approximate best proximity pairs in metric space with a directed graph [PDF]
Mathematica MoravicaLet (X,d) be a metric space endowed with a directed graph G where V (G) and E(G) represent the sets of vertices and edges corresponding to X, respectively.

A New Survey of Measures of Noncompactness and Their Applications
Axioms, 2022 We present a survey of the theory of measures of noncompactness and discuss some fixed point theorems of Darbo’s type. We apply the technique of measures of noncompactness to the characterization of classes of compact operators between certain sequence ...

Best Proximity Point Theorems for a Berinde MT-Cyclic Contraction on a Semisharp Proximal Pair [PDF]
International 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 given. Our results generalize and improve some known results in the literature.

Best Proximity Pair Theorems for Multifunctions with Open Fibres
Journal 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 \(\text{dist}(x_0, Tx_0)= \text{dist}(A,B)\).

Best proximity point for proximal Berinde nonexpansive mappings on starshaped sets [PDF]
, 2018 summary:In this paper, we introduce the new concept of proximal mapping, namely proximal weak contractions and proximal Berinde nonexpansive mappings. We prove the existence of best proximity points for proximal weak contractions in metric spaces, and ...

Structural constraints identified with covariation analysis in ribosomal RNA. [PDF]
PLoS ONE, 2012 Covariation analysis is used to identify those positions with similar patterns of sequence variation in an alignment of RNA sequences. These constraints on the evolution of two positions are usually associated with a base pair in a helix.

On a generalization of a relatively nonexpansive mapping and best proximity pair
Fixed Point Theory and Algorithms for Sciences and Engineering, 2023 AbstractLet A and B be two nonempty subsets of a normed space X, and let $T: A \cup B \to A \cup B$ T : A ∪ B → A ∪ B be a cyclic (resp., noncyclic) mapping.
