Coupled coincidence point results for (ψ,φ) -weakly contractive mappings in partially ordered Gb-metric spaces
Mustafa, Zead; Parvaneh, Vahid; Abbas, Mujahid; Roshan, Jamal Rezaei ( Hindawi Publishing Corporation , 2013 , Article)In this paper we present some coupled coincidence point results for (ψ,φ) -weakly contractive mappings in the setup of partially ordered Gb -metric spaces. Our results extend the results of Cho et al. (Fixed Point Theory ... -
Existence and approximation results for SKC mappings in CAT(0) spaces
Abbas, Mujahid; Khan, Safeer Hussain; Postolache, Mihai ( Springer International Publishing , 2014 , Article)Recently, Karap?nar and Tas (Comput. Math. Appl. 61:3370-3380, 2011) extended the class of Suzuki-generalized nonexpansive mappings to the class of SKC mappings. In this paper, we investigate SKC mappings to get a criterion ... -
Fixed point results for generalized chatterjea type contractive conditions in partially ordered G-metric spaces
Khan, Safeer Hussain; Abbas, Mujahid; Nazir, Talat ( Hindawi Publishing Corporation , 2014 , Article)In the framework of ordered G -metric spaces, fixed points of maps that satisfy the generalized Chatterjea type contractive conditions are obtained. The results presented in the paper generalize and extend several well ... -
A New One-Step Iterative Process for Common Fixed Points in Banach Spaces
Kim, Jong Kyu; Abbas, Mujahid; Khan, Safeer Hussain ( Hindawi Publishing Corporation , 2008 , Article)We introduce a new one-step iterative process and use it to approximate the common fixed points of two asymptotically nonexpansive mappings through some weak and strong convergence theorems. Our process is computationally ... -
On fixed points of Berinde's contractive mappings in cone metric spaces
Abbas, Mujahid; Vetro, Pasquale; Khan, Safeer Hussain ( North University of Baia Mare , 2010 , Article)In this paper we establish some common fixed point theorems for two self-mappings satisfying a generalized contractive condition. This result generalizes well known comparable results in the literature. As an application, ... -
Some coincidence point results for generalized (ψ,φ) -weakly contractive mappings in ordered G-metric spaces
Mustafa, Zead; Parvaneh, Vahid; Abbas, Mujahid; Roshan, Jamal Rezaei ( Hindawi Publishing Corporation , 2013 , Article)The aim of this paper is to present some coincidence point results for six mappings satisfying the generalized (ψ,φ) -weakly contractive condition in the framework of partially ordered G-metric spaces. To elucidate our ...
