Article Citation - WoS: 40Citation - Scopus: 46Some Fixed Point Results for Multi-Valued Mappings in b-metric Spaces(Springeropen, 2014) Kutbi, Marwan Amin; Karapinar, Erdal; Ahmad, Jamshaid; Azam, AkbarThe aim of this paper is to establish some fixed point theorems for set-valued mappings in the context of b-metric spaces. The proposed theorems expand and generalize several well-known comparable results in the literature. An example is also given to support our main result.Article Citation - WoS: 35Citation - Scopus: 46Some unique fixed point theorems for rational contractions in partially ordered metric spaces(Springeropen, 2013) Arshad, Muhammad; Karapinar, Erdal; Ahmad, JamshaidIn this paper, we prove some unique fixed point results for an operator T satisfying certain rational contraction condition in a partially ordered metric space. Our results generalize the main result of Jaggi (Indian J. Pure Appl. Math. 8(2):223-230, 1977). We give several examples to show that our results are proper generalization of the existing one. MSC: 47H10, 54H25, 46J10, 46J15.Article Citation - WoS: 27Some Common Fixed Point Results in Rectangular Metric Spaces(Hindawi Ltd, 2013) Arshad, Muhammad; Ahmad, Jamshaid; KarapJnar, ErdalWe obtain sufficient conditions for the existence of unique common fixed point of (psi-phi)-weakly contractive mappings on complete rectangular metric spaces. In the process, we generalize several fixed point results from the literature. We also give an example to illustrate our work.
