Remark on the system of nonlinear variational inclusions

open access: yesArab Journal of Mathematical Sciences, 2014
We prove the existence of a solution to the system of nonlinear variational inclusions problem. We provide examples of applications related to a coupled best approximations theorem for multivalued mappings and a multivalued coupled coincidence point.

Coincidence point theorems for $\varphi$-$\psi$-contraction mappings in metric spaces involving a graph

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2016
Some new coupled coincidence and coupled common fixed point theorems for $\varphi$-$\psi$-contraction mappings are established. We have also an application to some integral system to support the results.

Coupled fixed point‎, ‎$F$-invariant set and fixed point of $N$-order

open access: yesAnnals 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 ...

Steady-state stabilization due to random delays in maps with self-feedback loops and in globally delayed-coupled maps [PDF]

open access: yes, 2005
We study the stability of the fixed-point solution of an array of mutually coupled logistic maps, focusing on the influence of the delay times, $\tau_{ij}$, of the interaction between the $i$th and $j$th maps. Two of us recently reported [Phys. Rev. Lett.

Fixed point results of $(\phi,\psi)$-weak contractions in ordered $b$-metric spaces

open access: yesCubo, 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 ...

Infrared stability of ABJ-like theories [PDF]

open access: yes, 2009
We consider marginal deformations of the superconformal ABJM/ABJ models which preserve N=2 supersymmetry. We determine perturbatively the spectrum of fixed points and study their infrared stability.

The Strong Coupling Fixed-Point Revisited [PDF]

open access: yesJournal of the Physical Society of Japan, 2005
In recent work we have shown that the Fermi liquid aspects of the strong coupling fixed point of the s-d and Anderson models can brought out more clearly by interpreting the fixed point as a renormalized Anderson model, characterized by a renormalized level $\tilde _d$, resonance width, $\tilde $, and interaction $\tilde U$, and a simple prescription

Competing Boundary Interactions in a Josephson Junction Network with an Impurity [PDF]

open access: yes, 2010
We analyze a perturbation of the boundary Sine-Gordon model where two boundary terms of different periodicities and scaling dimensions are coupled to a Kondo-like spin degree of freedom. We show that, by pertinently engineering the coupling with the spin

Discussion on some coupled fixed point theorems [PDF]

open access: yesFixed Point Theory and Applications, 2013
The authors survey a possible list of coupled fixed point results in ordered metric spaces which, by a method used presumably for the first time in [\textit{V. Berinde}, Nonlinear Anal., Theory Methods Appl., Ser. A, Theory Methods 74, No. 18, 7347--7355 (2011; Zbl 1235.54024)], can be reduced to known results for mappings with one variable.
