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) ...
Binary Čech soft closure spaces
(Işık University Press, 2024-04)
In this paper the notion of binary Čech soft closure space which is defined over two initial universe sets with fixed sets of parameters is introduced and studied. This space extends and generalizes Čech soft closure space. ...
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 ...
On edge irregularity strength of ladder related graphs
(Işık University Press, 2024-04)
For a simple graph G, a vertex labeling φ : V (G) → {1, 2, . . . , k} is called k-labeling. The weight of an edge xy in G, written wφ(xy), is the sum of the labels of end vertices x and y, i.e., wφ(xy) = φ(x) + φ(y). A ...
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, ...
Solving inverse partial differential equations problems by using teaching learning based optimization algorithm
(Işık University Press, 2024-04)
In this paper, a numerical approach is combined with teaching learning based optimization algorithm (TLBO) to solve problems of inverse partial differential equations. The most important point in the way we have presented ...
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 ...
Generalized q-difference equation for the generalized q-operator rφs(Dq) and its applications in q-integrals
(Işık University Press, 2024-04)
In 2014, Fang [12] discovered a general q-exponential operator identity by solving a q-difference equation. Fang [12] developed some generalizations of q-integrals using this q-difference equation. Reshem and Saad [20] ...
Solvability of a resonant fractional-order p-Laplacian boundary value problem with two-dimensional kernel
(Işık University Press, 2024-04)
The goal of this study is to establish the existence of solutions for a fractionalorder p-Laplacian boundary value problem with a two-dimensional kernel at resonance case. The non-linearity of this problem forced us to ...
Algebraic sum and algebraic product of spherical neutrosophic sets
(Işık University Press, 2024-04)
The Spherical Neutrosophic Set is a generalization of Spherical Fuzzy Set. In this paper, we define Algebraic sum and Algebraic product of spherical neutrosophic sets (SNSs) and investigate their desirable properties. ...
