Common fixed point and common coupled fixed point theorems for weakly monotone mappings

Boletim da Sociedade Paranaense de Matemática
In this paper we have established two common fixed point theorems which are variants of the fixed point theorem of Boyd and Wong [On nonlinear contractions, Proc. Amer. Math. Soc. 20(1969), 458-464].

Nonlinear Contractive Conditions for Coupled Cone Fixed Point Theorems

Fixed Point Theory and Applications, 2010
We establish some new coupled fixed point theorems for various types of nonlinear contractive maps in the setting of quasiordered cone metric spaces which not only obtain several coupled fixed point theorems announced by many authors but also generalize ...

Coupled Potts models: Self-duality and fixed point structure

, 1999
We consider q-state Potts models coupled by their energy operators. Restricting our study to self-dual couplings, numerical simulations demonstrate the existence of non-trivial fixed points for 2

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.

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 ...

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.

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.
