Harmonic Mean Cordial labeling of some graphs
(Işık University Press, 2024-01)
All the graphs considered in this article are simple and undirected. Let G = (V(G), E(G)) be a simple undirected Graph. A function f : V (G) ? {1, 2} is called Harmonic Mean Cordial if the induced function f*: E(G) ? {1, ...
Total edge irregularity strength of join of path and complement of a complete graph
(Işık University Press, 2024-01)
An edge irregular total k-labeling of a graph G is a labeling of the vertices and edges of G with labels from the set {1, 2, ..., k} in such a way that any two different edges have distinct weights. The weight of an edge ...
On the monophonic and monophonic domination polynomial of a graph
(Işık University Press, 2024-01)
A set S of vertices of a graph G is a monophonic set of G if each vertex u of G lies on an u ? v monophonic path in G for some u, v ? S. M ? V (G) is said to be a monophonic dominating set if it is both a monophonic set ...
On connective eccentric matrix of a graph
(Işık University Press, 2024-01)
In the present paper, the connective eccentric matrix CE(G) for a simple connected graph G is introduced and bounds of spectral radius of CE(G) are obtained. The notion of connective eccentric energy ?(G) is also introduced ...
Hypergeometric function representation of the roots of a certain cubic equation
(Işık University Press, 2024-01)
The aim in this note is to obtain new hypergeometric forms for the functions (?z ? 1 ? ?z) b ± (?z ? 1 ? ?z)?b, (?z ? 1 + ?z)b ± (?z ? 1 + ?z)?b, where b is an arbitrary parameter, in terms of Gauss hypergeometric functions. ...
On the Cauchy problem for systems of linear equations of elliptic type of the first order in the space R?
(Işık University Press, 2024-04)
In the present paper, on the basis of the Carleman matrix, approximate solutions of the Cauchy problem for matrix factorizations of the Helmholtz equation are found in explicit form.
A novel simple 5D hyperchaotic system derived from the 3D Sprott C system
(Işık University Press, 2024-04)
A novel simple 5D hyperchaotic system with two non-hyperbolic equilibria points is presented. The proposed system is designed by coupling between a 3D Sprott C system and a 2D linear system via a coupling strategy. Compared ...
On almost convergence of fuzzy variables
(Işık University Press, 2024-04)
In this paper, within framework credibility theory, we examine several notions of convergence and almost convergence of fuzzy variable sequences. We investigate relations between these notions. Utilizing fuzzy variables, ...
Generalization of Picture Fuzzy Matrix
(Işık University Press, 2024-04)
In this paper, we introduce the concept of k-regular Picture Fuzzy Matrix (PiFuM) as a generalization of regular matrix and investigate some basic properties of a k-Regular Picture Fuzzy Matrix (k-RPiFuM). Moreover we ...
Secure point set domination in graphs
(Işık University Press, 2024-04)
In this paper, we introduce the notion of secure point-set domination in graphs. A point-set dominating D of graph G is called a secure point-set dominating set if for every vertex u ? V ?D, there exists a vertex v ? D?N(u) ...
