On a Common Jungck Type Fixed Point Result in Extended Rectangular b-Metric Spaces
Axioms, 2019 In this paper, we present a Jungck type common fixed point result in extended rectangular b-metric spaces. We also give some examples and a known common fixed point theorem in extended b-metric spaces.

Existence of Fuzzy Fixed Points and Common Fuzzy Fixed Points for
Mathematics, 2023 This article contains results of the existence of fuzzy fixed points of fuzzy mappings that satisfy certain contraction conditions using the platform of partial b-metric spaces. Some non-trivial examples are provided to authenticate the main results. The

Nuclear Physics B, 2022 We study the orientifold of the N=1 superconformal field theories describing D3-branes probing the Suspended Pinch Point singularity, as well as the orientifolds of non-chiral theories obtained by a specific orbifold Zn of SPP.

Dynamics and Bifurcation of $x_{n+1}=\frac{\alpha+\beta x_{n-2}}{A+Bx_{n}+C x_{n-2}}$
Journal of Mathematical Sciences and Modelling, 2021 In this paper, we study dynamics and bifurcation of the third order rational difference equation \begin{eqnarray*} x_{n+1}=\frac{\alpha+\beta x_{n-2}}{A+Bx_{n}+Cx_{n-2}}, ~~n=0, 1, 2, \ldots \end{eqnarray*} with positive parameters $\alpha, \beta, A, B ...

Fixed points and self-reference
International Journal of Mathematics and Mathematical Sciences, 1984 It is shown how Gödel's famous diagonal argument and a generalization of the recursion theorem are derivable from a common construation. The abstract fixed point theorem of this article is independent of both metamathematics and recursion theory and is ...

Existence of almost fixed points for random operators with application in game theory
Results in Nonlinear Analysis, 2020 We introduce the notion of the random ε-fixed point for random operators. Then we prove some existence theorems in order to apply this results in game theory for example we will prove existence of ε-random Nash equilibrium in some class of random games ...

Related G-metrics and Fixed Points
Annals of the West University of Timisoara: Mathematics and Computer Science, 2018 For a single valued mapping T in a G-complete G-metric space (X, d), we show that if Tn,for some n> 1, is a contraction, then T itself is a contraction under another related G-metric d′. We establish moreover that if T is uniformly continuous, then d′ is

Fixed Points in Functional Inequalities
Journal of Inequalities and Applications, 2009 Using fixed point methods, we prove the generalized Hyers-Ulam stability of the following functional inequalities ‖f(x)+f(y)+f(z)‖≤‖f(x+y+z)‖ and ‖f(x)+f(y)+2f(z)‖≤‖2f((x+y)/2+z)‖ ...
