Common Fixed Points Theorems for Self-Mappings in Menger PM-Spaces

Mathematics, 2022
The purpose of this paper is to prove that orbital continuity for a pair of self-mappings is a necessary and sufficient condition for the existence and uniqueness of a common fixed point for these mappings defined on Menger PM-spaces with a nonlinear ...

COMMON FIXED POINTS OF COMPATIBLE MAPPINGS

Demonstratio Mathematica, 1993
Extending results of the author [ibid. 23, No. 1, 213-218 (1990; Zbl 0731.54030)] and of \textit{B. E. Rhoades} [Some fixed point theorems for pairs of mappings, Jñānābha 15, 151-156 (1985)], some common fixed point theorems are established. Four mappings are involved satisfying a suitable expansive inequality in a complete metric space and a pairwise ...

COMMON FIXED POINT AND INVARIANT APPROXIMATION RESULTS [PDF]

Bulletin of the Korean Mathematical Society, 2007
Let \(X\) be a linear space. A \(p\)-norm on \(X\) is a real-valued function \(\|\cdot\|_p\) on \(X\) with \(0< p\leq 1\), satisfying {\parindent=7mm \begin{itemize}\item[(i)] \(\| x\|_p\geq 0\) and \(\| x\|_p= 0\) if and only if \(x= 0\), \item[(ii)] \(\| x+ y\|_p\leq\| x\|_p+\| y\|_p\), \item[(iii)] \(\|\lambda x\|_p= |\lambda|^p\| x\|_p\) for all ...

The MedSupport Multilevel Intervention to Enhance Support for Pediatric Medication Adherence: Development and Feasibility Testing

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction We developed MedSupport, a multilevel medication adherence intervention designed to address root barriers to medication adherence. This study sought to explore the feasibility and acceptability of the MedSupport intervention strategies to support a future full‐scale randomized controlled trial.

Common Fixed Points and Best Approximation

Journal of Approximation Theory, 1996
The subject of the fixed points of different systems is an intensively studied domain. It is also the case in the paper under review, which main purposes are to prove a fixed-point theorem generalizing results of Dotson and Habiniak and to extend, to generalize and unify these results on fixed points and common fixed points of best approximation.

Changes in Body Composition in Children and Young People Undergoing Treatment for Acute Lymphoblastic Leukemia: A Systematic Review and Meta‐Analysis

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Ongoing evidence indicates increased risk of sarcopenic obesity among children and young people (CYP) with acute lymphoblastic leukemia (ALL), often beginning early in treatment, persisting into survivorship. This review evaluates current literature on body composition in CYP with ALL during and after treatment.
