Caristi-Type Fixed Point Theorems and Some Generalizations on M-Metric Space
Altun, Ishak; Sahin, Hakan; Turkoglu, Duran (MALAYSIAN MATHEMATICAL SCIENCES SOC, 2020)In this paper, taking into account Caristi's fixed point results on both metric spaces and partial metric spaces, we present their some extensions and generalizations on M-metric spaces. First, by providing a counter ... -
A COMMON FIXED POINT THEOREM FOR WEAKLY COMPATIBLE MAPPINGS IN SYMMETRIC SPACES SATISFYING AN IMPLICIT RELATION
Turkoglu, Duran; Altun, Ishak (Soc Matematica Mexicana, 2007)In this paper, we prove a common fixed point theorem for weakly compatible mappings in symmetric spaces satisfying an implicit relation and a fixed point thorems under strict contractive conditions, J. Math. Anal. Appl. ... -
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. -
A fixed point theorem for weakly compatible mappings satisfying a general contractive condition of operator type
Altun, Ishak; Turkoglu, Duran (Charles Babbage Res Ctr, 2013)In this paper, we prove a fixed point theorem for weakly compatible mappings satisfying a general contractive condition of operator type. In short, we are going to study mappings A, B,S,T : X -> X for which there exists a ... -
Fixed points of weakly compatible maps satisfying a general contractive condition of integral type
Altun, Ishak; Turkoglu, Duran; Rhoades, Billy E. (Springer, 2007)We prove a fixed point theorem for weakly compatible maps satisfying a general contractive condition of integral type. Copyright (C) 2007. -
Some Fixed Point Theorems for Multi-Valued Weakly Uniform Increasing Operators
Altun, Ishak; Turkoglu, Duran (C E D A M Spa Casa Editr Dott Antonio Milani, 2008)In the present work, we introduce the concept of weakly uniform increasing operators on an ordered spaces. We also give some common fixed point theorems for a pair of multivalued weakly uniform increasing operators in ... -
SOME FIXED POINT THEOREMS FOR WEAKLY COMPATIBLE MAPPINGS SATISFYING AN IMPLICIT RELATION
Altun, Ishak; Turkoglu, Duran (Mathematical Soc Rep China, 2009)In this paper, we prove a common fixed point theorem for weakly compatible mappings satisfying an implicit relation. Our theorem generalizes many fixed point theorems. -
Some fixed point theorems for weakly compatible multi valued mappings satisfying an implicit relation
Altun, Ishak; Turkoglu, Duran (Univ Nis, Fac Sci Math, 2008)In this paper, we prove a common fixed point theorem for multivalued mappings under the condition of weak compatibility. Also, we define compatible maps of type (I) for multivalued mappings and prove a common fixed point ... -
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 ...
