Some fixed points of multivalued maps in multiplicative metric spaces (original) (raw)

Some Unique Fixed Point Theorems in Multiplicative Metric Spaces

\"{O}zavsar and Cevikel(Fixed point of multiplicative contraction mappings on multiplicative metric space.arXiv:1205.5131v1 [math.GN] 23 may 2012)initiated the concept of the multiplicative metric space in such a way that the usual triangular inequality is replaced by "multiplicative triangle inequality [Math Processing Error] for all [Math Processing Error]". In this manuscript, we discussed some unique fixed point theorems in the context of multiplicative metric spaces. The established results carry some well known results from the literature to multiplicative metric space. We note that some fixed point theorems can be deduced in multiplicative metric space by using the established results. Appropriate examples are also given.

Fixed points of multiplicative contraction mappings on multiplicative metric spaces

Journal of Engineering and Technology, 2017

In this paper, we first discussed multiplicative metric mapping by giving some topological properties of the relevant multiplicative metric space. As an interesting result of our discussions, we observed that the set of positive real numbers R_+ is a complete multiplicative metric space with respect to the multiplicative absolute value function. Furthermore, we introduced concept of multiplicative contraction mapping and proved some fixed point theorems of such mappings on complete multiplicative metric spaces.

Remarks on Multiplicative Metric Spaces and Related Fixed Points

arXiv: General Topology, 2015

In this article we studied the relationship between metric spaces and multiplicative metric spaces. Also, we pointed out some fixed and common fixed point results under some contractive conditions in multiplicative metric spaces can be obtained from the corresponding results in standard metric spaces.

Some related fixed point theorems for multivalued mappings on two metric spaces

Carpathian Mathematical Publications, 2020

The definition of related mappings was introduced by Fisher in 1981. He proved some theorems about the existence of fixed points of single valued mappings defined on two complete metric spaces and relations between these mappings. In this paper, we present some related fixed point results for multivalued mappings on two complete metric spaces. First we give a classical result which is an extension of the main result of Fisher to the multivalued case. Then considering the recent technique of Wardowski, we provide two related fixed point results for both compact set valued and closed bounded set valued mappings via FFF-contraction type conditions.

Common fixed point results for compatible-type mappings in multiplicative metric spaces

Journal of Nonlinear Sciences and Applications, 2016

In this paper, we prove some common fixed point theorems for generalized contractive mappings satisfying some conditions, that is, compatible and compatible-type mappings in multiplicative metric spaces. Our results improve and generalize the corresponding results given in the literature. Moreover, we give some examples to illustrate our main results.

Fixed points of multivalued mappings in metric spaces

2019

Admissibility of mappings are introduced to create conditions to minimally restrict various contractive conditions on pairs of points from a metric space in order to ensure fixed point property of the respective contractions. In the present work we define new admissibility conditions and control functions to obtain certain multivalued fixed point theorems. The corresponding single valued case is discussed. We define four weak contraction mappings of which two are multivalued and two are single valued. The results are without any assumption of continuity. There is an illustrative example.

Fixed point and common fixed point theorems of contractive multivalued mappings on complete metric spaces

2011

In this paper we give a common fixed point type generalization for some multi-valued contractive mappings on complete metric spaces. Our results extend some recent results of Y. Feng, S. Liu[ Y. Feng and S. Liu, Fixed point theorem of multi-valued contractive mappings, J. Fixed point theorems for set valued contractions in complete metric spaces, J. Math. Anal. Appl. 334(2007)132-139]. We show that some common fixed point contraction theorems for multi-valued mappings are straightforward consequence of our results.

Some fixed point results for multivalued operators in generalized metric spaces

Computers & mathematics with applications, 2011

Recently, Bucur, Guran and Petrusel presented some results on fixed points of multivalued operators on generalized metric spaces which extended some old fixed point theorems to the multivalued case (Bucur et al., 2009 [7]). Also, Kikkawa and Suzuki have proved some results for generalized contractions in complete metric spaces (Kikkawa, 2008 [9]). In this paper, we shall give some results on fixed points of multivalued operators on generalized metric spaces by using the method of Kikkawa (2008) [9].

Fixed point results in multiplicative generalized metric spaces

Advances in Fixed Point Theory, 2016

In this paper, first we introduce the notion of multiplicative generalized metric spaces and then prove the Banach contraction principle in setting of newly defined spaces. We also introduce the notion of weakly commuting, compatible maps and its variants, weakly compatible, weakly compatible with properties (E.A) and CLR in this space. Further, we prove some fixed point theorems on multiplicative generalized metric spaces and provide some suitable examples in support of our results.
