Game-Theoretic Model of SARS Precautions

Leslie J. Camacho Aquino, Aurienne Cruz, Regina-Mae Dominguez et al.

Kyungpook Mathematical Journal 2024; 64: 371-393

Severe Acute Respiratory Syndrome (SARS) is a highly contagious viral disease with high mortality rate. There is no vaccine against SARS, but the spread can be limited by masking or social distancing. In this paper we implement a game-theoretic model...

The Exponential Representations of Pell and Its Generalized Matrix Sequences

Sukran Uygun

Kyungpook Mathematical Journal 2024; 64: 395-405

In this paper we define a matrix sequence called the Pell matrix sequence whose elements consist of Pell numbers. Using a positive parameter k, we generalize the Pell matrix sequence to a k-Pell matrix sequence and using two parameters ...

Key Words:

Pell numbers, matrix sequences, generalized sequences, exponential matrices

Problems in the Geometry of the Siegel-Jacobi Space

Jae-Hyun Yang

Kyungpook Mathematical Journal 2024; 64: 407-416

The Siegel-Jacobi space is a non-symmetric homogeneous space which is very important geometrically and arithmetically. In this short paper, we propose the basic problems in the geometry of the Siegel-Jacobi space.

A Note on Noetherian Polynomial Modules

Jung Wook Lim

Kyungpook Mathematical Journal 2024; 64: 417-421

Let R be a commutative ring and let M be an R-module. In this note, we give a brief proof of the Hilbert basis theorem for Noetherian modules. This states that if R contains the identity and M is a Noetherian unitar...

Some Aspects of λ-△^m-Statistical Convergence on Neutrosophic Normed Spaces

Reena Antal*, Meenakshi Chawla

Kyungpook Mathematical Journal 2024; 64: 461-478

Neutrosophication is a useful tool for handling real-world problems with partially dependent, partially independent, and even independent components. By examining some properties related to λ-statistical convergence on neutrosophic normed spac...
