Article Citation - WoS: 9Some Tripled Coincidence Point Theorems for Almost Generalized Contractions in Ordered Metric Spaces(Tamkang Univ, 2013) Aydi, Hassen; Karapinar, Erdal; Mustafa, ZeadIn this paper, we prove tripled coincidence and common fixed point theorems for F: X x X x X -> X and g: X -> X satisfying almost generalized contractions in partially ordered metric spaces. The presented results generalize the theorem of Berinde and Borcut [Tripled fixed point theorems for contractive type mappings in partially ordered metric spaces, Nonlinear Anal. 74 (15) (2011) 4889-4897. Also, some examples are presented.Article Citation - WoS: 21Citation - Scopus: 22Quadruple Fixed Point Theorems Under Nonlinear Contractive Conditions in Partially Ordered Metric Spaces(Hindawi Ltd, 2012) Karapinar, Erdal; Shatanawi, Wasfi; Mustafa, ZeadWe prove a number of quadruple fixed point theorems under phi-contractive conditions for a mapping F : X-4 -> X in ordered metric spaces. Also, we introduce an example to illustrate the effectiveness of our results.Article Citation - WoS: 19Citation - Scopus: 14Coupled coincidence point results on generalized distance in ordered cone metric spaces(Springer, 2013) Aydi, Hassen; Karapinar, Erdal; Mustafa, ZeadIn this paper, we establish some coupled coincidence point results in the setting of partially ordered cone metric spaces via -distance. We also proved some related coupled common fixed point theorems for such mappings. Our results generalize, extend, and unify several well-known comparable results in the literature regarding this topic. We present some examples to illustrate the concepts and results.
