Coupled fixed point sets with data-dependence and stability [PDF]
Surveys in Mathematics and its Applications, 2022 In this paper we establish a coupled fixed point theorem of a coupled multivalued mapping defined on a complete metric space. In our result we use a new contractive inequality. There are rational terms in the expression of the inequality. The contractive

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 ...

Fixed point results for $G^m$-Meir-Keeler contractive and $G$-$(\alpha,\psi)$-Meir-Keeler contractive mappings [PDF]
, 2013 In this paper, first we introduce the notion of a $G^m$-Meir-Keeler contractive mapping and establish some fixed point theorems for the $G^m$-Meir-Keeler contractive mapping in the setting of $G$-metric spaces. Further, we introduce the notion of a $G_c^

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 ...

Contractive mappings are Kannan mappings, and Kannan mappings are contractive mappings in some sense [PDF]
, 2005 In this paper, we prove that a mapping \(T\) on a metric space is contractive with respect to a \(\tau\)-distance if and only if it is Kannan with respect to a \(\tau ...

Diametrically Contractive Multivalued Mappings [PDF]
Fixed Point Theory and Applications, 2007 AbstractDiametrically contractive mappings on a complete metric space are introduced by V. I. Istratescu. We extend and generalize this idea to multivalued mappings. An easy example shows that our fixed point theorem is more applicable than a former one obtained by H. K. Xu.

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.

Fixed Point Index for Simulation Mappings and Applications
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2023 In this paper, we construct the fixed point index for a class of contractive mapping defined by a simulation mapping and a measure of noncompact-ness noted by Zµ− contraction maps.

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.
