    Existence and Uniqueness of Common Coupled Fixed Point Results Via Auxiliary Functions
    (Springer Singapore Pte Ltd, 2014) Chandok, S.; Karapinar, E.; Khan, M. Saeed; Mathematics
    The purpose of this paper is to establish some coupled coincidence point theorems for mappings having a mixed g-monotone property in partially ordered metric spaces. Also, we present a result on the existence and uniqueness of coupled common fixed points. The results presented in the paper generalize and extend several well-known results in the literature.

    On Reich Type Λ - Α-Nonexpansive Mapping in Banach Spaces With Applications To l1<
    (Univ Politecnica Valencia, Editorial Upv, 2018) Belbaki, Rabah; Karapinar, E.; Ould-Hammouda, Amar
    In this manuscript we introduce a new class of monotone generalized nonexpansive mappings and establish some weak and strong convergence theorems for Krasnoselskii iteration in the setting of a Banach space with partial order. We consider also an application to the space L-1([0, 1]). Our results generalize and unify the several related results in the literature.

    Automatic Continuity of Surjective n-homomorphisms on Banach Algebras
    (Iranian Mathematical Soc, 2015) Gordji, M. Eshaghi; Jabbari, A.; Karapinar, E.; Mathematics
    In this paper, we show that every surjective n-homomorphism (n-anti-homomorphism) from a Banach algebra A into a semisimple Banach algebra B is continuous.

    On Modified Α-Φ Meir-Keeler Contractive Mappings
    (Univ Nis, Fac Sci Math, 2014) Salimi, P.; Hussain, N.; Roldan, A.; Karapinar, E.
    Samet et al. [Nonlinear Anal. 75: 2154-2165, 2012] introduced and studied alpha-psi-contractive mappings. More recently Salimi, et al. [Fixed Point Theory Appl., 2013: 151] modified the notion of alpha-psi-contractive mappings and improved the fixed point theorems in [20, 32]. Here we utilize these notions to establish fixed point results for modified alpha-phi-asymmetric Meir-Keeler contractions and triangular alpha-admissible mappings defined on G-metric and cone G-metric spaces. Several interesting consequences of our theorems are also provided here to illustrate the usability of the obtained results.

    On the Fixed Point Theorems for Generalized Weakly Contractive Mappings On Partial Metric Spaces
    (Springer Singapore Pte Ltd, 2013) Chi, K. P.; Karapinar, E.; Thanh, T. D.; Mathematics
    In this paper, we prove a fixed point theorem for a pair of generalized weakly contractive mappings in complete partial metric spaces. The are generalizations of very recent fixed point theorems due to Abdeljawad, Karapmar and Tas.
