Electronic Journal of Qualitative Theory of Differential Equations, 2012 In this paper, a generalization of Nadler's fixed point theorem is presented for $H^+$-type $k$-multi-valued weak contractive mappings. We consider a nonconvex Hammerstein type integral inclusion and prove an existence theorem by using an $H^+$-type ...

Abstract and Applied Analysis, 2022 In this paper, common best proximity point theorems for weakly contractive mapping in b-metric spaces in the cases of nonself-mappings are proved; we introduced the notion of generalized proximal weakly contractive mappings in b-metric spaces and proved ...

WEAKLY CONTRACTIVE MAPPING IN PARTIAL METRIC SPACE
, 2017 Contractive mapping is one kind of mapping that guarantees a fixed point in a metric space Many experts has developed this kind of mapping to show the existence of a fixed point such as Kannan mapping and Chatterjea Contractive mapping.

, 2022 The best proximity point is a generalization of a fixed point that is beneficial when the contraction map is not a self-map. On other hand, best approximation theorems provide an approximate solution to the fixed-point equation Tҳ = ҳ.

Graphical approach to the study of fixed point results involving hybrid contractions
Results in Control and OptimizationIn this work, a new class of general contractive mappings, with the name Jaggi-Suzuki-type hybrid (K-α-ϕ)-contractive mapping is discussed in metric space equipped with a graph and new criteria for which the mapping is a Picard operator are studied.

A Bibliometric Analysis of Publications in Uremic Toxins From 1991 to 2024
Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Uremic toxins are a growing area of research in nephrology, with significant implications in the progression and treatment of chronic kidney disease (CKD) and the management of end‐stage kidney disease (ESKD). This bibliometric analysis aims to evaluate the global research trends, key contributors, and the impact of publications in ...

Fixed points of asymptotically contractive mappings
, 1992 Let X and Y be metric spaces. We say that a continuous mapping T: X → Y is asymptotically-k-contractive if limn, m; n ≠ md(Txn, Txm) ⩽ k limn, m; n ≠ md(xn, xm) for every sequence {xn} such that both limits exist.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
FEBS Letters, EarlyView.This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Fixed point theorems on certain class of contractive mappings [PDF]
, 1988 The objective of this paper is to introduce the concepts of a H-contractive mapping and a π -ultimately contractive mapping on cartesian product of two metric spaces, and to show that, under certain restrictions, such mappings have a fixed ...
