Fixed point and coupled fixed point theorems on b-metric-like spaces [PDF]
Journal of Inequalities and Applications, 2013 Abstract We first introduce the concept of b-metric-like space which generalizes the notions of partial metric space, metric-like space and b-metric space. Then we establish the existence and uniqueness of fixed points in a b-metric-like space as well as in a partially ordered b-metric-like space.

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 ...

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 ...

Coupled fixed point sets with data-dependence and stability [PDF]
Surveys in Mathematics and its Applications, 2022 In this paper we establish a coupled fixed point theorem of a coupled multivalued mapping defined on a complete metric space. In our result we use a new contractive inequality. There are rational terms in the expression of the inequality. The contractive

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

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 $\Lambda$.

Coupled Fixed Point Theorems under Weak Contractions
Discrete Dynamics in Nature and Society, 2012 Cho et al. [Comput. Math. Appl. 61(2011), 1254–1260] studied common fixed point theorems on cone metric spaces by using the concept of c-distance. In this paper, we prove some coupled fixed point theorems in ordered cone metric spaces by using the ...
