FIXED POINT RESULTS FOR MULTIVALUED MAPPINGS OF FENG-LIU TYPE ON M-METRIC SPACES
Altun, Ishak; Sahin, Hakan; Turkoglu, Duran (MATHEMATICAL RESEARCH PRESS-MATH RES, 2018)In this paper, we present some fixed point theorems for multivalued mappings of Feng-Liu type on complete M-metric spaces. Some illustrative examples are also provided to support our main results. -
Locally Convex Valued Rectangular Metric Spaces and The Kannan's Fixed Point Theorem
Abdeljawad, Thabet; Turkoglu, Duran (EUDOXUS PRESS, LLC, 2012)Rectangular TVS-cone metric spaces are introduced and Kannan's fixed point theorem is proved in these spaces. Two approaches are followed for the proof. At first we prove the theorem by a direct method using the structure ... -
A note on common fixed points for (psi, alpha, beta)-weakly contractive mappings in generalized metric spaces
Bilgili, Nurcan; Karapinar, Erdal; Turkoglu, Duran (SPRINGER INTERNATIONAL PUBLISHING AG, 2013)Very recently, Isik and Turkoglu (Fixed Point Theory Appl. 2013:131, 2013) proved a common fixed point theorem in a rectangular metric space by using three auxiliary distance functions. In this paper, we note that this ... -
(psi, phi) -weak Contraction on Ordered Uniform Spaces
Turkoglu, Duran; Ozturk, Vildan (UNIV NIS, FAC SCI MATH, 2014)In this paper, we prove a fixed point theorem for (psi, phi) -contractive mappings on ordered uniform space. -
Some Caristi type fixed point theorems
Aslantas, Mustafa; Sahin, Hakan; Turkoglu, Duran (Springernature, 2021)In 1976, Caristi fixed point theorem was proved for ordinary metric spaces. After that, it was shown that this result is equivalent to Ekeland variational principle which has a great number of applications in many branches ... -
Some Ciric Type Periodic Point Results with Q-function on Quasi Metric Spaces
Sahin, Hakan; Turkoglu, Duran (Amer Inst Physics, 2021)In this paper, we proved a Ciric type periodic point result with a Q-function on quasi metric spaces. We also give an illustrative example to show the effectiveness of our main result. -
Two fixed point results for multivalued F-contractions on M-metric spaces
Sahin, Hakan; Altun, Ishak; Turkoglu, Duran (SPRINGER-VERLAG ITALIA SRL, 2019)In this article, by considering Feng-Liu's technique, we present new fixed point results for multivalued mappings which are regarding to F-contraction on M-complete M-metric space. Then, we provide some nontrivial examples ...
