A novel approach to determining chromatic number induced by labelings

Gee-Choon Lau, Wai Chee Shiu, Zhen Bin Gao

Given a simple graph $G = (V, E)$ of order $p$ and size $q$ , a bijection $f : V \cup E \to {1, 2, \dots, p + q}$ is a local total neighborhood antimagic labeling of $G$ if the induced…

Feedback Diagonalization and Stabilization for Discrete Linear Ensemble Systems

Jonathan M. Bosnich, Xudong Chen

We consider a countably infinite collection of linear, scalar control systems, where each system is represented by the pair $(a_{n}, b_{n})$ with $a_{n} > 0$ for $n \in N$ , and all…

On local antimagic chromatic number of the join of two special families of graphs -- II

Gee-Choon Lau, Wai Chee Shiu

It is known that null graphs and 1-regular graphs are the only regular graphs without local antimagic chromatic number. In this paper, we proved that the join of 1-regular graph an…
