Approaches Which Output Infinitely Many Graphs With Small Local Antimagic Chromatic Number

Gee-Choon Lau, Jianxi Li, Ho-Kuen Ng +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…
