Coupled fixed point, $F$-invariant set and fixed point of $N$-order
Annals of Functional Analysis, 2010 In this paper, we establish some new coupled fixed point theorems in complete metric spaces, using a new concept of $F$-invariant set. We introduce the notion of fixed point of $N$-order as natural extension of that of coupled fixed point. As applications, we discuss and adapt the presented results to the setting of partially ordered cone ...

A variational principle, coupled fixed points and market equilibrium
Nonlinear Analysis: Modelling and Control, 2021 We present a possible kind of generalization of the notion of ordered pairs of cyclic maps and coupled fixed points and its application in modelling of equilibrium in oligopoly markets. We have obtained sufficient conditions for the existence and uniqueness of coupled fixed in complete metric spaces.

Contraints on Matter from Asymptotic Safety
, 2002 Recent studies of the ultraviolet behaviour of pure gravity suggest that it admits a non-Gaussian attractive fixed point, and therefore that the theory is asymptotically safe.

On Coupled Fixed Point Theorems for Nonlinear Contractions in Partially Ordered -Metric Spaces
Abstract and Applied Analysis, 2012 Two concepts—one of the coupled fixed point and the other of the generalized metric space—play a very active role in recent research on the fixed point theory.

Exact Strongly Coupled Fixed Point in $g\varphi^4$ Theory
, 2015 We show explicitly how a strongly coupled fixed point can be constructed in scalar $g\varphi^4$ theory from the solutions to a non-linear eigenvalue problem.

Existence theorems of coupled fixed points
Journal of Mathematical Analysis and Applications, 1991 AbstractBy associating with a mixed monotone operator a monotone operator on product space, several existence theorems of coupled fixed points are proved.

Critical behavior of supersymmetric O(N) models in the large-N limit [PDF]
, 2011 We derive a supersymmetric renormalization group (RG) equation for the scale-dependent superpotential of the supersymmetric O(N) model in three dimensions.

Coupled Fixed-Point Theorems in Theta-Cone-Metric Spaces
Journal of Mathematics, 2021 This paper gives further generalizations of some well-known coupled fixed-point theorems. Specifically, Theorem 3 of the paper is the generalization of the Baskar–Lackshmikantham coupled fixed-point theorem, and Theorem 5 is the generalization of the ...
