Common fixed point of mappings satisfying almost generalized (S,T)-contractive condition in partially ordered partial metric spaces
Shobkolaei, N.; Sedghi, S.; Roshan, J. R.; Altun, I. (Elsevier Science Inc, 2012)In this paper, we present the concept of almost generalized (S,T)-contractive condition, and combine this idea with the concept of partial metric and prove some common fixed point results in such spaces. An example is ... -
Fixed Point Results For α-Admissible Multivalued F -Contractions
Durmaz, G.; Altun, I. (Univ Miskolc Inst Math, 2016)In this study, we give some fixed point results for multivalued mappings using Pompeiu-Hausdorff distance on complete metric space. For this, we consider the alpha-admissibility of multivalued mappings. Our results are ... -

Sedghi, S.; Altun, I.; Shobe, N. (Univ Belgrade, Fac Electrical Engineering, 2008)We present a fixed point theorem for multi-valued mapping satisfying an implicit relation on metric spaces. -
Fixed-Point Theorems for Integral-Type Contractions on Partial Metric Spaces
Sabetghadam, F.; Masiha, H. P.; Altun, I. (Springer, 2016)We present some fixed-point results for single-valued mappings on partial metric spaces satisfying a contractive condition of integral type. -

A New Approach to Caristi's Fixed Point Theorem on Non-Archimedean Fuzzy Metric Spaces
Sedghi, S.; Shobkolaei, N.; Altun, I. (Univ Sistan & Baluchestan, 2015)In the present paper, we give a new approach to Caristi's fixed point theorem on non-Archimedean fuzzy metric spaces. For this we define an ordinary metric d using the non-Archimedean fuzzy metric M on a nonempty set X and ... -
On A General Class Of Weakly Picard Operators
Altun, I.; Hancer, H. A.; Minak, G. (Univ Miskolc Inst Math, 2015)In this paper we show that on complete metric spaces the class of weakly Picard operators contains some operators which are more general than the class of almost contractions. -
Some coincidence point results in ordered b-metric spaces and applications in a system of integral equations
Roshan, J. R.; Parvaneh, V.; Altun, I. (Elsevier Science Inc, 2014)The aim of this paper is to present some coincidence point results for four mappings satisfying generalized (psi, phi)-weakly contractive condition in the framework of ordered b-metric spaces. An example and an application ... -
Some fixed point results for multivalued F-contractions on quasi metric spaces
In the present paper, taking into account recent conractive technique, which is called F-contraction, we provide some new fixed point results for multivalued mapping on some kind of complete quasi metric spaces. -
Some fixed point theorems for maps with fuzzy distance in uniform space
Shobkolaei, N.; Sedghi, S.; Altun, I. (Springer, 2013)The purpose of this paper is to define the notion of fuzzy A-distance in uniform spaces and give several new common fixed point results for weakly compatible contractive or expansive selfmappings on uniform spaces. -
Some fixed point theorems for single and multi valued mappings on ordered non-Archimedean fuzzy metric spaces
Altun, I. (Univ Sistan & Baluchistan, 2010)In the present paper, a. partial order on a non- Archimedean fuzzy metric, space under the Lukasiewicz t-norm is introduced and fixed point theorem's for single and multivalued mappings are proved. -

Suzuki Type Fixed Point Result for Rational theta-Contraction on Complete Metric Spaces
Durmaz, G.; Minak, G.; Altun, I. (Southeast Asian Mathematical Soc-Seams, 2019)In this paper, we present a new approach to fixed point theorems for single valued contraction mappings defined on complete metric spaces. We introduce a new concept called Suzuki type rational theta*-contraction and prove ...
