A fixed point problem via simulation functions in incomplete metric spaces with its application
(Işık University Press, 2020)
In this paper, firstly, we review the notion of the SO-complete metric spaces. This notion let us to consider some fixed point theorems for single-valued mappings in incomplete metric spaces. Secondly, as motivated by the ...
Fixed point results from soft metric spaces and soft quasi metric spaces to soft G-metric spaces
(Işık University Press, 2020)
In this paper, soft quasi-metric spaces by means of soft elements are described. Also the presentation of soft G-metric spaces and the existing fixed point results of contractive mappings defined on this kind of spaces are ...
Locally and weakly contractive principle in bipolar metric spaces
(Işık University Press, 2020)
In this article, we introduce concepts of (?, ?)-uniformly locally contractive and weakly contractive mappings, which are generalizations of Banach contraction mapping, in bipolar metric spaces. Also, we express the results ...
Stability and data dependence results for Zamfirescu multi-valued mappings
(Işık University Press, 2020)
In this paper, we prove some stability and data dependence results for the class of multivalued Zamfirescu operators. Our results generalize and improve several existing results in literature. It is worth mentioning here ...
Generalized fixed point results with multi-valued mappings
(Işık University Press, 2020)
In this article we deduce fixed point results for multi-valued contraction mappings. We primarily established two fixed results. One of them is the generalization of Nadler’s contraction and the other result is the ...
A strong convergence for finding a common fixed point of a representation of nonexpansive mappings and w-mappings in banach spaces
(Işık University Press, 2020)
In this paper, a strong convergence for finding an element of the set of common fixed points of a representation and W-mappings of nonexpansive mappings is introduced. Then, the strong convergence of the proposed implicit ...
Existence of fixed point and best point of proximity for multifunctional non self mappings in a partial metric space
(Işık University Press, 2021)
In this paper we give some theorems of existence of best points of proximity for a multifunctional non-self-mapping in a partial metric space and some approximations on the sets of the best points of proximity. Other results ...
Nabla fractional boundary value problem with a non-local boundary condition
(Işık University Press, 2024-01)
In this work, we deal with the following two-point boundary value problem for a finite fractional nabla difference equation with non-local boundary condition: (?(???(e) u(z) = p(z, u(z)), z ? Nfe+2, u(e) = g(u), u(f) = 0. ...
On some novel results for C-weak-fuzzy contractions
(Işık University Press, 2023-04)
This article implements the idea of introducing the concept of C-weak-fuzzy contraction mapping in the framework of fuzzy cone metric spaces, and deriving some unique common fixed point results. A nontrivial example is ...
Generalized contractive mappings on quasimetric spaces
(Işık University Press, 2023-04)
In this paper, we introduce a new class of generalized contractive mappings to establish a fixed point theorem for this class of mappings in complete quasimetric spaces. In fact, at first we present the notion of ordered ...
