Local Antimagic Chromatic Number of Middle Graph and Direct Product of Graphs

Huimin Xu, Gee-Choon Lau, Ruixue Zhang

An edge labeling of a connected graph $G = (V, E)$ is called a local antimagic labeling if it is a bijection $f : E \to {1, 2, \dots, ∣ E ∣}$ such that for any…

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 $y$ , $f^{+} (x) \neq = f^{+} (y)$ …

Complete characterization of s-bridge graphs with local antimagic chromatic number 2

Gee-Choon Lau, Wai-Chee Shiu, Ruixue Zhang +2

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…

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…
