    A note on some coupled fixed-point theorems on G-metric spaces
    (Springeropen, 2012) Ding, Hui-Sheng; Karapinar, Erdal
    The purpose of this paper is to extend some recent coupled fixed-point theorems in the context of G-metric space by essentially different and more natural way. We state some examples to illustrate our results.

    A Note on Recent Fixed Point Results Involving g-quasicontractive Type Mappings in Partially Ordered Metric Spaces
    (Springer international Publishing Ag, 2014) Karapinar, Erdal; Samet, Bessem
    In this note, we establish the equivalence between recent fixed point theorems involving quasicontractive type mappings in metric spaces endowed with a partial order.

    A Note on '(g, f)-closed Set and Tripled Point of Coincidence Theorems for Generalized Compatibility in Partially Metric Spaces'
    (Springeropen, 2014) Karapinar, Erdal; Roldan-Lopez-de-Hierro, Antonio-Francisco
    Recently, some (common) multidimensional fixed theorems in partially ordered complete metric spaces have appeared as a generalization of existing (usual) fixed point results. Unexpectedly, we realized that most of such (common) coupled fixed theorems are either weaker or equivalent to existing fixed point results in the literature. In particular, we prove that the results included in the very recent paper (Charoensawan and Thangthong in Fixed Point Theory Appl. 2014:245, 2014) can be considered as a consequence of existing fixed point theorems on the topic in the literature.

    On Coupled Fixed Point Theorems on Partially Ordered g-metric Spaces
    (Springeropen, 2012) Karapinar, Erdal; Kaymakcalan, Billur; Tas, Kenan
    In this manuscript, we extend, generalize and enrich some recent coupled fixed point theorems in the framework of partially ordered G-metric spaces in a way that is essentially more natural.
