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 ...

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.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Chemotherapy‐induced peripheral neuropathy remains a major complication in pediatric cancer, with disrupted somatosensory and nociceptive processing being a key aspect. This review synthesizes empirical studies on alterations in somatosensory and nociceptive processing in children and adolescents with cancer.

On a fixed point theorem of Greguš
International Journal of Mathematics and Mathematical Sciences, 1986 We consider two selfmaps T and I of a closed convex subset C of a Banach space X which are weakly commuting in X, i.e.‖TIx−ITx‖≤‖Ix−Tx‖ for any x in X,and satisfy the inequality‖Tx−Ty‖≤a‖Ix−Iy‖+(1−a)max{‖Tx−Ix‖,‖Ty−Iy‖}for all x, y in C, where ...

Common α-Fuzzy Fixed Point Results for F-Contractions with Applications
Mathematics, 2021 F-contractions have inspired a branch of metric fixed point theory committed to the generalization of the classical Banach contraction principle. The study of these contractions and α-fuzzy mappings in b-metric spaces was attempted timidly and was not ...

A Common Fixed Point Theorem Using an Iterative Method [PDF]
Sahand Communications in Mathematical Analysis, 2020 Let $ H$ be a Hilbert space and $C$ be a closed, convex and nonempty subset of $H$. Let $T:C rightarrow H$ be a non-self and non-expansive mapping. V. Colao and G.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Introduction Adolescent siblings of children with cancer are at elevated risk for psychosocial problems. Unfortunately, various barriers such as limited family time and resources, conflicting schedules, and psychosocial staffing constraints at cancer centers hinder sibling access to support.

A common fixed point theorem for a sequence of fuzzy mappings
International Journal of Mathematics and Mathematical Sciences, 1995 We obtain a common fixed point theorem for a sequence of fuzzy mappings, satisfying a contractive definition more general than that of Lee, Lee, Cho and Kim [2].

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
