Bipolar intuitionistic fuzzy CK compact spaces

Nandhini, R.; Amsaveni, D. (Işık University Press, 2022)

The objective of this article is to initiate the innovative views on bipolar intuitionistic fuzzy topological space, bipolar intuitionistic fuzzy C compact and its preimage, orbit and image followed by some of its special ...

Numerical solution of second order linear hyperbolic telegraph equation

Kirli, Emre; Irk, Dursun; Zorşahin Görgülü, Melis (Işık University Press, 2022)

This paper is of about a numerical solution of the second order linear hyperbolic telegraph equation. To solve numerically the second order linear hyperbolic telegraph equation, the cubic B-spline collocation method is ...

The mean reverting Ornstein-Uhlenbeck processes with nonlinear autoregressive drift term innovations

Nabati, Parisa (Işık University Press, 2022)

The main purpose of this paper is to present a new approach for energy markets governed by a two-factor Ornstein-Uhlenbeck process with a stochastic nonlinear autoregressive drift term innovation and an unknown diffusion ...

Some results on graceful centers of Pn and related α-graceful graphs

Hardik, Makadia; Kaneria, Vinodrai; Andharia, Pritesh; Jadeja, Divyaba (Işık University Press, 2022)

In this paper, we have proved that the graph obtained by joining two copies of a bipartite graceful graph by an edge with any two corresponding vertices of both the copies of graphs is α-graceful. We also proved path step ...

On leap Zagreb indices of some cycle related graphs

Natarajan, Chidambaram; Selvamuthukumaran, S.; Farahani, Mohammad Reza (Işık University Press, 2022)

Let G = (V, E) represent a graph. The 2-degree of a vertex v in G is the number of vertices which are at distance two from v and denoted by d₂(v). The leap Zagreb indices are the recently introduced distance-based topological ...

A novel third kind Chebyshev wavelet collocation method for the numerical solution of stochastic fractional Volterra integro-differential equations

Shiralashetti, Siddu; Lamani, Lata (Işık University Press, 2022)

In the formulation of natural processes like emissions, population development, financial markets, and the mechanical systems, in which the past affect both the present and the future, Volterra integro-differential equations ...

Almost periodic positive solutions for a delayed nonlinear density dependent mortality Nicholson’s blowflies model on time scales

Rajendra Prasad, Kapula; Khuddush, Mahammad; Vidyasagar, Kuparala Venkata (Işık University Press, 2022)

In this paper we discuss a nonlinear density dependent mortality Nicholson’s blowflies equation with multiple pairs of time varying delays. By contraction mapping theorem, we derived the necessary conditions for the existence ...

‘Del’ relation and parallelism in fuzzy lattices

Wasadikar, Meenakshi Pralhadrao; Khubchandani, Payal Ashok (Işık University Press, 2022)

The notions of ‘del’ relation, a neutral element and parallelism from lattice theory are introduced in a fuzzy lattice and their properties are obtained.

Fixed point theorems of fuzzy partial metric spaces

Tehlan, Aanchal; Kumar, Vijay (Işık University Press, 2022)

Fuzzy metric space has been defined using fuzzy numbers by many researchers. Recently Xia and Guo [20] have introduced fuzzy metric space using fuzzy scalars which is similar to the classical metric space. In this work we ...

Determination of a nonlinear source term in a reaction-diffusion equation by using finite element method and radial basis functions method

Zeidabadi, Hamed; Pourgholi, Reza; Hosseini, Abbas (Işık University Press, 2022)

In this paper, two numerical methods are presented to solve a nonlinear inverse parabolic problem of determining the unknown reaction term in the scalar reactiondiffusion equation. In the first method, the finite element ...

Introduction to total dominator edge chromatic number

Alikhani, Saeid; Ghanbari, Nima (Işık University Press, 2022)

We introduce the total dominator edge chromatic number of a graph G. A total dominator edge coloring (briefly TDE-coloring) of G is a proper edge coloring of G in which each edge of the graph is adjacent to every edge of ...

Sharma, Karnika; Bhat, Vijay Kumar (Işık University Press, 2022)

In this study, the orbits of non abelian metabelian groups of order 26, 28 and 30 are found using conjugation action. The non abelian metabelian groups considered in this study are some dihedral groups D₁₃, D₁₄ and D₁₅ as ...

Changing and unchanging on Tadpole domination number in G − e, G + e graphs

Al-Harere, Manal Naji; Khuda Bakhash, P. A. (Işık University Press, 2022)

In this paper, the effect of “Tadpole domination” change is examined, which is one of the domination types, when a graph is modified, by deleting or adding an edge in G. This edge deletion may represent a cut in a network. ...
