Weak proximal normal structure and coincidence quasi-best proximity points
Applied General Topology, 2020 We introduce the notion of pointwise cyclic-noncyclic relatively nonexpansive pairs involving orbits. We study the best proximity point problem for this class of mappings.

Discussion on “Multidimensional Coincidence Points” via Recent Publications
Abstract and Applied Analysis, 2014 We show that some definitions of multidimensional coincidence points are not compatible with the mixed monotone property. Thus, some theorems reported in the recent publications (Dalal et al., 2014 and Imdad et al., 2013) have gaps. We clarify these gaps

Coupled fixed points of (ϕˆ,ψˆ,θˆ)-contractive mappings in partially ordered b-metric spaces
Heliyon, 2022 We aim to prove the existence and uniqueness of the fixed points for the self mappings satisfying generalized contractions involving altering distance functions in ordered metric type space.

Coincidence points of mappings in Banach spaces [PDF]
Fixed Point Theory, 2020 In this article we prove an existence theorem for coincidence points of mappings in Banach spaces. This theorem generalizes the Kantorovich fixed point theorem.

Coincident-point rigidity in normed planes
Ars Mathematica Contemporanea, 2023 A bar-joint framework $(G,p)$ is the combination of a graph $G$ and a map $p$ assigning positions, in some space, to the vertices of $G$. The framework is rigid if every edge-length-preserving continuous motion of the vertices arises from an isometry of the space.

Results of the Childhood Cancer and Leukaemia Group's United Kingdom Relapsed Wilms Tumour Trial
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background The United Kingdom relapsed Wilms tumour (UKW‐R) trial aimed to improve the historically low survival rates after relapse of Wilms tumour (WT) through a prospective national risk‐stratified protocol. The trial also evaluated efficacy and toxicity of high‐dose melphalan.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Purpose Cognitive and psychological difficulties could negatively interfere with treatment adherence and quality of life before and after hematopoietic stem cell transplant (HSCT). Methods to mitigate these changes may have positive effects on treatment success.

MAPS PRESERVING THE COINCIDENCE POINTS OF OPERATORS
EURASIAN MATHEMATICAL JOURNAL, 2021 Summary: Let \(\mathcal{B(X)}\) be the algebra of all bounded linear operators on a Banach space \(\mathcal{X}\) with \(\dim \mathcal{X} \geqslant 2\). In this paper, we describe surjective maps \(\phi: \mathcal{B(X)}\to\mathcal{B(X)}\) preserving the coincidence points of operators, i.e., \(C(A,B)=C(\phi(A),\phi(B))\), for every \(A, B \in \mathcal{B ...
