Fixed point theorems under Pata-type conditions in metric spaces
Journal of the Egyptian Mathematical Society, 2016 In this paper, we prove a generalization of Chatterjea’s fixed point theorem, based on a recent result of Pata. Also, we establish common fixed point results of Pata-type for two maps, as well as a coupled fixed point result in ordered metric spaces.

Coupled fixed point theorems of JS-G-contraction on G-metric spaces
Boletim da Sociedade Paranaense de Matemática, 2022 Jaradat has proven some fixed point results using JS-G-contraction on $G-$metric spaces. Choudhury et al. were derived coupled fixed point theorems for the $G-$metric spaces.

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.

Existence Result For a Model Coupling a Quasi-Linear Parabolic Equation and a Linear Hyperbolic System [PDF]
arXiv, 2022 We prove globally-in-time existence of solution for a problem coupling the linear Lam\'e system and the quasi-linear Stokes equation. A solution of this global coupled problem is viewed as the fixed point of some non-linear operator $T$. We construct, using a regularization procedure, a sequence $(T^\epsilon)_\epsilon$ of auxiliary approximating ...

Amplitude death in coupled chaotic oscillators [PDF]
Phys. Rev. E 72, 056204 (2005), 2005 Amplitude death can occur in chaotic dynamical systems with time-delay coupling, similar to the case of coupled limit cycles. The coupling leads to stabilization of fixed points of the subsystems. This phenomenon is quite general, and occurs for identical as well as nonidentical coupled chaotic systems.

Seven Largest Couplings of the Standard Model as IR Fixed Points [PDF]
Physical Review Letters, 2019 We report on an intriguing observation that the values of all the couplings in the standard model except those related to first two generations can be understood from the IR fixed point structure of renormalization group equations in the minimal supersymmetric model extended by one complete vectorlike family with the scale of new physics in a multi-TeV

Fixed point results of $(\phi,\psi)$-weak contractions in ordered $b$-metric spaces
Cubo, 2022 The purpose of this paper is to prove some results on fixed point, coincidence point, coupled coincidence point and coupled common fixed point for the mappings satisfying generalized $(\phi, \psi)$-contraction conditions in complete partially ordered ...

FEBS Letters, EarlyView.In vivo IL‐10 produced by tissue‐resident tolDC is involved in maintaining/inducing tolerance. Depending on the agent used for ex vivo tolDC generation, cells acquire common features but prime T cells towards anergy, FOXP3+ Tregs, or Tr1 cells according to the levels of IL‐10 produced. Ex vivo‐induced tolDC were administered to patients to re‐establish/

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.

Fixed-Point Structure of Scalar Fields [PDF]
Phys.Rev.Lett. 74 (1995) 3526-3529, 1994 We search for alternatives to the trivial $\phi^4$ field theory by including arbitrary powers of the self-coupling. Such theories are renormalizable when the natural cutoff dependencies of the coupling constants are taken into account. We find a continuum of fixed points, which includes the well-known Gaussian fixed point. The fixed point density has a
