A coupled coincidence point theorem in partially ordered metric spaces with an implicit relation
Gulyaz, Selma; Karapinar, Erdal; Yuce, Ilker Savas (SPRINGER INTERNATIONAL PUBLISHING AG, 2013)In this manuscript, we discuss the existence of a coupled coincidence point for mappings and , where F has the mixed gmonotone property, in the context of partially ordered metric spaces with an implicit relation. Our ... 
A COUPLED FIXED POINT RESULT IN PARTIALLY ORDERED PARTIAL METRIC SPACES THROUGH IMPLICIT FUNCTION
Gulyaz, Selma; Karapinar, Erdal (HACETTEPE UNIV, FAC SCI, 2013)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 ... 
Existence of a solution of integral equations via fixed point theorem
Gulyaz, Selma; Karapinar, Erdal; Rakocevic, Vladimir; Salimi, Peyman (SPRINGEROPEN, 2013)In this paper, we establish a solution to the following integral equation: u(t) = integral(T)(0) G(t, s)f(s, u(s)) ds for all t is an element of [0,T], (1) where T > 0, f : [0, T] x R > R and G : [0, T] x [0, T] > [0, ... 
Existence of solutions of integral equations via fixed point theorems
Gulyaz, Selma; Erhan, Inci M. (SPRINGER INTERNATIONAL PUBLISHING AG, 2014)Existence and uniqueness of fixed points of a mapping defined on partially ordered Gmetric spaces is discussed. The mapping satisfies contractive conditions based on certain classes of functions. The results are applied ... 
Fixed Point Theorems for a Class of alphaAdmissible Contractions and Applications to Boundary Value Problem
Alsulami, Hamed H.; Gulyaz, Selma; Karapinar, Erdal; Erhan, Inci M. (HINDAWI PUBLISHING CORPORATION, 2014)A class of alphaadmissible contractions defined via altering distance functions is introduced. The existence and uniqueness conditions for fixed points of such maps on complete metric spaces are investigated and related ... 
FIXED POINTS OF alpha  psi CONTRACTION MAPPINGS ON QUASIbMETRICLIKE SPACES
Gulyaz, Selma (YOKOHAMA PUBL, 2016)In this paper, we consider fixed point for the mapping of alpha  psi contractions in the setting of quasibmetriclike space. Some fixed point theorems are investigated in quasibmetriclike spaces. 
Fixed points of alphaadmissible MeirKeeler contraction mappings on quasimetric spaces
Alsulami, Hamed H.; Gulyaz, Selma; Erhan, Inci M. (SPRINGER INTERNATIONAL PUBLISHING AG, 2015)We introduce alphaadmissible MeirKeller and generalized alphaadmissible MeirKeller contractions on quasimetric spaces and discuss the existence of fixed points of such contractions. We apply our results to Gmetric ... 
Generalized alpha MeirKeeler Contraction Mappings on Branciari bmetric Spaces
Gulyaz, Selma; Karapinar, Erdal; Erhan, Inci M. (UNIV NIS, FAC SCI MATH, 2017)In this paper, alphaMeirKeeler and generalized alphaMeirKeeler contractions on Branciari bmetric spaces are introduced. Existence and uniqueness of fixed points of such contractions are discussed and related theorems ... 
An Ulam stability result on quasibmetriclike spaces
Alsulami, Hamed H.; Gulyaz, Selma; Karapinar, Erdal; Erhan, Inci M. (SCIENDO, 2016)In this paper a class of general type alphaadmissible contraction mappings on quasibmetriclike spaces are defined. Existence and uniqueness of fixed points for this class of mappings is discussed and the results are ...
