Editorial Citation Count: 1Existence and uniqueness of fixed point in various abstract spaces and related applications(Hindawi Publishing Corporation, 2015) Karapınar, Erdal; Du,W.-S.; Kumam,P.; Petruşel,A.; Romaguera,S.; Mathematics[No abstract available]Article Citation Count: 5An extension of generalized (ψ,φ)-weak contractions(2012) Karapınar, Erdal; Chi,K.P.; Karapnar,E.; Thanh,T.D.; MathematicsWe prove a fixed-point theorem for a class of maps that satisfy generalized (ψ,φ) -weak contractions depending on a given function. An example is given to illustrate our extensions. © 2012 Tran Van An et al.Article Citation Count: 14Some nonunique common fixed point theorems in symmetric spaces through CLR (S,T) property(2013) Karapınar, Erdal; Patel,D.K.; Imdad,M.; Gopal,D.; MathematicsWe introduce a new class of mappings satisfying the "common limit range property" in symmetric spaces and utilize the same to establish common fixed point theorems for such mappings in symmetric spaces. Our results generalize and improve some recent results contained in the literature of metric fixed point theory. Some illustrative examples to highlight the realized improvements are also furnished. © 2013 E. Karapnar et al.Article Citation Count: 20Tripled coincidence point theorems for nonlinear contractions in partially ordered metric spaces(2012) Karapınar, Erdal; Karapnar,E.; Kundu,A.; MathematicsTripled fixed points are extensions of the idea of coupled fixed points introduced in a recent paper by Berinde and Borcut, 2011. Here using a separate methodology we extend this result to a triple coincidence point theorem in partially ordered metric spaces. We have defined several concepts pertaining to our results. The main results have several corollaries and an illustrative example. The example shows that the extension proved here is actual and also the main theorem properly contains all its corollaries.
