Fixed Point Results for Multi-Valued Contractions in b−Metric Spaces and an Application
Mathematics, 2019 In this paper, by characterizing a weak contractive condition based on using C − functions and α − admissible multi-valued mapping of type S, we present some fixed point results for ( α , F ) − admissible multi-valued mappings in the setting of b ...

Fisher type fixed point results in controlled metric spaces
, 2020 In the present paper, we define a rational contractive condition of Fisher type in the context of controlled metric space and obtain some generalized fixed point results in this space.

Fixed Point Results for Dualistic Contractions with an Application [PDF]
Discrete Dynamics in Nature and Society, 2020 In this paper, by introducing a convergence comparison property of a self-mapping, we establish some new fixed point theorems for Bianchini type, Reich type, and Dass-Gupta type dualistic contractions defined on a dualistic partial metric space. Our work generalizes and extends some well known fixed point results in the literature.

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 ...

Multivalued Pseudo-Picard Operators and Fixed Point Results
Journal of Function Spaces and Applications, 2013 We introduce the concept of multivalued pseudo-Picard (MPP) operator on a metric space. This concept is weaker than multivalued weakly Picard (MWP) operator, which is given by M. Berinde and V. Berinde (2007).

New Fixed Point Results via a Graph Structure
Mathematics, 2021 The main aim of this paper is to introduce and study some fixed point results for rational multivalued G-contraction and F-Khan-type multivalued contraction mappings on a metric space with a graph. At the end, we give an illustrative example.

Theory and Application of Fixed Point [PDF]
, 2021 In the past few decades, several interesting problems have been solved using fixed point theory. In addition to classical ordinary differential equations and integral equation, researchers also focus on fractional differential equations (FDE) and ...

Some Remarks on Multidimensional Fixed Point Theorems
, 2014 MARTINEZ-MORENO, JUAN/0000-0002-3340-2781In this paper, we show that most of the multidimensional (including coupled, tripled, quadrupled) fixed point theorems in the context of (ordered) metric spaces are, in fact, immediate consequences of well-known ...

On Fixed Point Results in Partial b-Metric Spaces
Journal of Function Spaces, 2021 Partial b-metric spaces are characterised by a modified triangular inequality and that the self-distance of any point of space may not be zero and the symmetry is preserved.
