A remark on Jleli–Samet’s best proximity point theorems for α-ψ-contraction mappings
Fixed Point Theory and Algorithms for Sciences and Engineering, 2023 Inspired by the work of Jachymski, we slightly extend some fixed point theorems with a graph and show that some best proximity point theorems for α-ψ-contraction mappings of Jleli and Samet can be deduced by our results.

Quench dynamics across quantum critical points [PDF]
, 2003 We study the quantum dynamics of a number of model systems as their coupling constants are changed rapidly across a quantum critical point. The primary motivation is provided by the recent experiments of Greiner et al. (Nature 415, 39 (2002)) who studied

Prešić Type Nonself Operators and Related Best Proximity Results
Mathematics, 2019 The purpose of this article is to discuss the existence of best proximity points for Pre s ˇ i c ´ -type nonself operators, say T : A k → B . We also give several examples to support our results.

Best proximity point theorems for generalized proximal contractions [PDF]
Fixed Point Theory and Applications, 2012 This paper deals with best proximity points of mappings \(T\) with no fixed points, that is, mappings for which the equation \(Tx=x\) does not need to have a solution and then the interest is to find such points \(x\) minimizing \(d(x,Tx)\). The typical situation in this paper is a mapping \(T: A\to B\) where \(A\) and \(B\) are non-empty subsets of a ...

SOME COMMENTS ON BEST PROXIMITY POINTS FOR ORDERED PROXIMAL CONTRACTIONS
Journal of Applied Analysis & Computation, 2022 Summary: In this article, we focus on the existence of an optimal approximate solution, designated as a best proximity point for non-self mappings which are ordered proximal contractions in the setting of partially ordered metric spaces and prove that these results are particular cases of existing fixed point theorems in the literature.

FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Best proximity points revisited
Filomat, 2019 In this paper, using the concept of w-distance on a metric space, we prove some new best proximity point results for the mappings of Meir-Keeler type. As an application, we derive some recent best proximity point results of the aforementioned type.

Best proximity point theorems for rational proximal contractions [PDF]
Fixed Point Theory and Applications, 2013 Abstract We provide sufficient conditions which warrant the existence and uniqueness of the best proximity point for two new types of contractions in the setting of metric spaces. The presented results extend, generalize and improve some known results from best proximity point theory and fixed-point theory.
