Numerical Nonlinear Stability of TravelingWaves for a Chemotaxis Model

Min-Gi Lee

Kyungpook Mathematical Journal 2023; 63: 141-154

We study the stability of traveling waves of a certain chemotaxis model. The traveling wave solution is a central object of study in a chemotaxis model. Kim et al. [8] introduced a model on a population and nut...

Weakly Right IQNN Rings

Yang Lee, Sang Bok Nam, Zhelin Piao∗

Kyungpook Mathematical Journal 2023; 63: 175-186

In this article we look at the property of a 2 by 2 full matrix ring over the ring of integers, of being weakly right IQNN. This generalisation of the property of being right IQNN arises from products of idempotents and nilpotents. W...

Quasinormal Subgroups in Division Rings Radical over Proper Division Subrings

Le Qui Danh∗, Trinh Thanh Deo

Kyungpook Mathematical Journal 2023; 63: 187-198

The motivation for this study comes from a question posed by I.N. Herstein in the Israel Journal of Mathematics in 1978. Specifically, let D be a division ring with center F. The aim of this paper is to demonstrate t...
