Vector-valued metrics, fixed points and coupled fixed points for nonlinear operators [PDF]
Fixed Point Theory and Applications, 2013 Abstract In this paper, we will present fixed point theorems for singlevalued and multivalued operators in spaces endowed with vector-valued metrics, as well as a Gnana Bhaskar-Lakshmikantham-type theorem for the coupled fixed point problem, associated to a pair of singlevalued operators (satisfying a generalized mixed monotone property) in ...

Coupled fixed point theorems under new coupled implicit relation in Hilbert spaces
Demonstratio Mathematica, 2022 The aim of this paper is to study existence and uniqueness of coupled fixed point for a family of self-mappings satisfying a new coupled implicit relation in a Hilbert space. We also prove well-posedness of a coupled fixed point problem.

Advances 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 ...

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

α-Coupled Fixed Points and Their Application in Dynamic Programming [PDF]
Abstract and Applied Analysis, 2014 We introduce the definition ofα-coupled fixed point in the space of the bounded functions on a setSand we present a result about the existence and uniqueness of such points. Moreover, as an application of our result, we study the problem of existence and uniqueness of solutions for a class of systems of functional equations arising in dynamic ...

The Strong Coupling Fixed-Point Revisited [PDF]
Journal 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

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

Exact results for non-holomorphic masses in softly broken supersymmetric gauge theories [PDF]
, 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 $\Lambda$.
