    Note on “modified Α-Ψ Mappings With Applications”
    (Chiang Mai University, 2015) Berzig,M.; Karapinar,E.
    In this short paper, we unexpectedly notice that the modified version of α-ψ-contractivemappings, suggested by Salimi et al. [Modified α-ψ-contractive mappings with applications, Fixed Point Theory and Applications 2013, 2013:151] is not a real generalization. © 2015 by the Mathematical Association of Thailand.

    On ćirić type φ-geraghty contractions
    (Chiang Mai University, 2019) Alqahtani,B.; Fulga,A.; Karapınar,E.
    In this paper we introduce the notions of φ-Geraghty contractions and Ćirić type φ-Geraghty contractions. We also investigate under which conditions such mappings posses a unique fixed point in the framework of complete metric spaces. We consider examples to show the validity of our main results. © 2019 by the Mathematical Association of Thailand.

    Rational Contractive Mappings of Integral Type on b-metric Spaces
    (Univ Prishtines, 2017) Alsulami, Hamed H.; Karapinar, Erdal; Piri, Hossien; Rahrovi, Samira; Zarghami, Ramazan
    The aim of this paper is to introduce (alpha, psi)- rational contractive mappings of integral type and analyze the existence of fixed points for these mappings in b-metric spaces. Our results extend the results in Karapinar et al. [35] and well known fixed point theorems in the literature.

    Fixed Points on Quasi-Metric Spaces Via Simulation Functions and Consequences
    (Univ Prishtines, 2018) Aydi, Hassen; Felhi, Abdelbasset; Karapinar, Erdal; Alojail, Fatimah A.
    In this paper, we provide some fixed points for triangular alpha-admissible contraction mappings via simulations functions in the class of quasimetric spaces. Some consequences are presented. We also give some illustrated examples.
