Common Fixed-Point and Fixed-Circle Results for a Class of Discontinuous F-Contractive Mappings †

Mathematics, 2022
The exploration of contractive inequalities which do not imply the continuity of the mapping at fixed points was an interesting open problem for quite some time.

Fixed Point and Common Fixed Point Theorems for α-Property in Cone Ball-Metric Spaces

International Journal of Analysis and Applications, 2013
In this paper, we define a new cone ball-metric and get fixed points and common fixed points for the α- property in cone ball-metric spaces.

Common fixed points for semigroups of mappings [PDF]

Proceedings of the American Mathematical Society, 1973
Let X be a compact convex subset of a strictly convex Banach space. Let S be a Hausdorff topological semigroup which is either left amenable or left reversible. Then for any generalised nonexpansive (jointly) continuous action of S on X, X contains a common fixed point of S.

Sickle Cell Disease Is an Inherent Risk for Asthma in a Sibling Comparison Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Sickle cell disease (SCD) and asthma share a complex relationship. Although estimates vary, asthma prevalence in children with SCD is believed to be comparable to or higher than the general population. Determining whether SCD confers an increased risk for asthma remains challenging due to overlapping symptoms and the ...

Some fixed point results for nonlinear contractive conditions in ordered proximity spaces with an application

AIMS Mathematics, 2023
In this article, we use the concept of proximity spaces to prove common fixed point results for mappings satisfying generalized ($ \psi $, $ \beta $)-Geraghty contraction type mapping in partially ordered proximity spaces.

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.
