Construction of local antimagic 3-colorable graphs of fixed even size -- matrix approach

Gee-Choon Lau, Wai Chee Shiu, M. Nalliah +1

An edge labeling of a connected graph $G = (V, E)$ is said to be local antimagic if it is a bijection $f : E \to {1, \dots, ∣ E ∣}$ such that for any pair of adjacent vertices $x$ and…

Constructions of local antimagic 3-colorable graphs of fixed odd size | matrix approach

Gee-Choon Lau, Wai Chee Shiu, K. Premalatha +1

An edge labeling of a connected graph $G = (V, E)$ is said to be local antimagic if there is a bijection $f : E \to {1, \dots, ∣ E ∣}$ such that for any pair of adjacent vertices $x$ …

On bridge graphs with local antimagic chromatic number 3

W. C. Shiu, G. C. Lau, R. X. Zhang

Let $G = (V, E)$ be a connected graph. A bijection $f : E \to {1, \dots, ∣ E ∣}$ is called a local antimagic labeling if for any two adjacent vertices $x$ and $y$ , $f^{+} (x) \neq = f^{+} (y)$ …

A note on local antimagic chromatic number of lexicographic product graphs

Gee-Choon Lau, Wai-Chee Shiu, K. Premalatha +2

Let $G = (V, E)$ be a connected simple graph. A bijection $f : E \to {1, 2, \dots, ∣ E ∣}$ is called a local antimagic labeling of $G$ if $f^{+} (u) \neq = f^{+} (v)$ holds for any two…

On local antimagic chromatic number of cycle-related join graphs II

Gee-Choon Lau, K. Premalatha, S. Arumugam +1

An edge labeling of a graph $G = (V, E)$ is said to be local antimagic if it is a bijection $f : E \to {1, \dots, ∣ E ∣}$ such that for any pair of adjacent vertices $x$ and $y$ , $f^+…

Sufficient spectral conditions on Hamiltonian and traceable graphs

Ruifang Liu, Wai Chee Shiu, Jie Xue

In this paper, we give sufficient conditions on the spectral radius for a bipartite graph to Hamiltonian and traceable, which expand the results of Lu, Liu and Tian (2012) [10]. Fu…
