New Families of tripartite graphs with local antimagic chromatic number 3

Gee-Choon Lau, Wai Chee Shiu

For a graph $G (V, E)$ of size $q$ , a bijection $f : E (G) \to [1, q]$ is a local antimagc labeling if it induces a vertex labeling $f^{+} : V (G) \to N$ such that $f^+(u) \ne f^…

On local antimagic total chromatic number of certain one point union of graphs

Gee-Choon Lau

Let $G = (V, E)$ be a connected simple graph of order $p$ and size $q$ . A bijection $f : V (G) \cup E (G) \to {1, 2, \dots, p + q}$ is called a local antimagic total labeling of $G$ if for…

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…
