New intuitionistic fuzzy 2- normed I-convergent double sequence spaces by bounded linear operator
(Işık University Press, 2021)
Saadati and Park [Saadati. R, and Park J. H., Chaos, Solitons Fractals 2006] [14] introduced the notion of intuitionistic fuzzy normed space. Motivated by this, we introduce some intuitionistic fuzzy 2-normed I-convergent ...
Fixed points in φ-ordered partial quasi-metric space
(Işık University Press, 2021)
We obtain fixed points for an order preserving mapping in a preordered left p-complete partial quasi-metric space using a preorder induced by an appropriate function. In particular, we do not make use of any contraction condition.
Cm-supermagic labeling of friendship graphs
(Işık University Press, 2021)
The friendship graph F?n is obtained by joining n copies of the cycle graph Cm with a common vertex. In this work, we investigate the Cm-supermagic labeling of friendship graphs.
Harmonic reciprocal status index and coindex of graphs
(Işık University Press, 2021)
The reciprocal status of a vertex u is defined as the sum of reciprocal of the distances between u and all other vertices of a graph G. In this paper we have defined the harmonic reciprocal status index and coindex of a ...
A comparative study of numerical solution of pantograph equations using various wavelets techniques
(Işık University Press, 2021)
The objective of the present article is to discuss a numerical method based on wavelets for finding the solution of pantograph differential equations with proportional delays. First, the pantograph differential equation ...
An approximation technique for first Painlevé equation
(Işık University Press, 2021)
In this study, we introduce a new approximative algorithm to get numerical solutions of the nonlinear first Painlevé equation. Indeed, to obtain an approximate solution, a combination of exponential matrix method based on ...
The method of fundamental solutions for the inverse time-dependent perfusion coefficient problem
(Işık University Press, 2021)
This paper deals with an inverse problem associated with the bio-heat equation in living tissue in the human body. The inverse problem consists of the identification of time-dependent perfusion coefficient when the exact ...
Common fixed point theorems under rational contractions using two mappings and six mappings and coupled fixed point theorem in bicomplex valued b-metric space
(Işık University Press, 2021)
During the past decades, enormous works by different researchers have been carried out in fixed point theory on metric spaces. In this paper, we prove some common fixed point theorems in bicomplex valued metric space for ...
The Re-nnd solutions of the matrix equation AxB = C with reference to indefinite inner product
(Işık University Press, 2021)
In this paper, we first consider the matrix equation AXA[?] = C , where A ? Cn×m, C ? Cn×n and establish necessary and sufficient conditions for the existence of Re-nnd solutions. Further, we determine the necessary and ...
Minimal restrained monophonic sets in graphs
(Işık University Press, 2021)
For a connected graph G = (V, E) of order at least two, a restrained monophonic set S of a graph G is a monophonic set such that either S = V or the subgraph induced by V ?S has no isolated vertices. The minimum cardinality ...
