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) ...
On the norms of r-circulant matrices involving balancing and Lucas-balancing numbers
(Işık University Press, 2024-04)
In this article, we investigate the r-circulant matrices B[r] and C[r] involving the balancing and Lucas-balancing numbers respectively with arithmetic indices. For matrices B[r] and C[r], we establish the direct formula ...
Nullity and energy of the cubic power graph
(Işık University Press, 2024-04)
Let G be a finite abelian group with identity 0, G1 = {3t | t ? G} ? G and G2 = G \ G1. The cubic power graph ?cpg of G is an undirected simple graph with vertex set G, such that two distinct vertices x and y are adjacent ...
Coefficient estimate of the second Hankel determinant of logarithmic coefficients for the subclass of close-to-convex function
(Işık University Press, 2024-04)
Let S denote the subclass of the analytic function and univalent functions in D, where D is defined as a unit disk, and having the Taylor representation form of S. In this paper, we will be obtaining the second Hankel ...
New vertex-edge sombor, Nirmala and Misbalance indices
(Işık University Press, 2024-04)
The molecular structure of a compound contains all the information which would help to determine its chemical, biological, and physical properties. With the help of a theoretical descriptor tool known as topological indices, ...
Optimal management of a prey-predator system in a polluted environment with effort shared between pollution reduction and harvesting
(Işık University Press, 2024-04)
This paper is concerned with the optimal management of a prey-predator system in a polluted environment with effort allocated between pollution reduction and prey harvesting. The growth rates of species and, consequently, ...
Fitted computational method for convection dominated diffusion equations with shift arguments
(Işık University Press, 2024-04)
A time dependent singularly perturbed convection diffusion equation involving shift parameters are considered. The terms containing the shifts are treated using Taylor series approximation up to second order terms. Classical ...
