Coupled fixed point analysis in fuzzy cone metric spaces with an application to nonlinear integral equations

open access: yesAdvances in Difference Equations, 2020
In this paper, we introduce the concept of coupled type and cyclic coupled type fuzzy cone contraction mappings in fuzzy cone metric spaces. We establish some coupled fixed point results without the mixed monotone property, and also present some coupled ...

Existence of Solutions for a System of Integral Equations Using a Generalization of Darbo’s Fixed Point Theorem

open access: yesMathematics, 2020
In this paper, an extension of Darbo’s fixed point theorem via θ -F-contractions in a Banach space has been presented. Measure of noncompactness approach is the main tool in the presentation of our proofs.

Fixed point theorems for generalized weakly contractive mappings in metric spaces with applications

open access: yesFixed Point Theory and Applications, 2018
In this paper, motivated and inspired by Samet et al., we introduce the notion of generalized weakly contractive mappings in metric spaces and prove the existence and uniqueness of fixed point for such mappings, and we obtain a coupled fixed point ...

Caristi Type Cyclic Contraction and Coupled Fixed Point Results in Bipolar Metric Spaces [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2020
In this paper, we establish the existence of common coupled fixed point results for new Caristi type contraction of three covariant mappings in Bipolar metric spaces. Some interesting consequences of our results are achieved.

Critical behavior of supersymmetric O(N) models in the large-N limit [PDF]

open access: yes, 2011
We derive a supersymmetric renormalization group (RG) equation for the scale-dependent superpotential of the supersymmetric O(N) model in three dimensions.

open access: yesBMC Research Notes, 2020
Objectives The aim of this paper is to establish some fixed point, coincidence point and, coupled coincidence and coupled common fixed point results for generalized $$(\phi , \psi )$$ ( ϕ , ψ ) -contractive mappings in partially ordered b-metric spaces ...

Coupled Fixed Point Results in Banach Spaces with Applications

open access: yesMathematics, 2021
The aim of this work is to discuss the existence of solutions to the system of fractional variable order hybrid differential equations. For this reason, we establish coupled fixed point results in Banach spaces.

Exact results for non-holomorphic masses in softly broken supersymmetric gauge theories [PDF]

open access: yes, 1998
We consider strongly coupled supersymmetric gauge theories softly broken by the addition of gaugino masses $m_\lambda$ and (non-holomorphic) scalar masses $m^2$, taken to be small relative to the dynamical scale $\Lambda$.

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>
