    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.

    A Coupled Fixed Point Result in Partially Ordered Partial Metric Spaces Through Implicit Function
    (Hacettepe Univ, Fac Sci, 2013) Gulyaz, Selma; Karapinar, Erdal; Mathematics
    In this manuscript, we discuss the existence of coupled fixed points in the context of partially ordered metric spaces through implicit relations for mappings F:X x X -> X such that F has the mixed monotone property. Our main theorem improves and extends various results in the literature. We also state an example to illustrate our work.

    Common Fixed Point Theorems in Cone Banach Spaces
    (Hacettepe Univ, Fac Sci, 2011) Abdeljawad, Thabet; Karapinar, Erdal; Tas, Kenan; Mathematics
    Recently, E. Karapinar (Fixed Point Theorems in Cone Banach Spaces, Fixed Point Theory Applications, Article ID 609281, 9 pages, 2009) presented some fixed point theorems for self-mappings satisfying certain contraction principles on a cone Banach space. Here we will give some generalizations of this theorem.

    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 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.
