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.

A scenario for the c>1 barrier in non-critical bosonic strings [PDF]

open access: yes, 1996
The c1 matrix models are analyzed within large N renormalization group, taking into account touching (or branching) interactions. The c0 is naturally associated with an unstable fixed point, separating the Liouville phase (gamma1.

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 ...

Some stability results for coupled fixed point iterative process in a complete metric space [PDF]

open access: yesSurveys in Mathematics and its Applications, 2019
In the paper [M. O. Olatinwo, Stability of coupled fixed point iterations and the continuous dependence of coupled fixed points, Communications on Applied Nonlinear Analysis 19 (2012), 71-83], the author has extended the notion of stability of fixed ...

Quantum entanglement and fixed-point bifurcations [PDF]

open access: yes, 2005
How does the classical phase space structure for a composite system relate to the entanglement characteristics of the corresponding quantum system? We demonstrate how the entanglement in nonlinear bipartite systems can be associated with a fixed point ...

Fixed points and coupled fixed points in partially ordered ν-generalized metric spaces

open access: yesApplied General Topology, 2018
<p>New fixed point and coupled fixed point theorems in partially ordered ν-generalized metric spaces are presented. Since the product of two ν-generalized metric spaces is not in general a ν-generalized metric space, a different approach is needed than in the case of standard metric spaces.</p>

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 ...

Contraints on Matter from Asymptotic Safety

open access: yes, 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.
