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…

Further Results On k-Super Graceful Graphs

Gee-Choon Lau, Wai-Chee Shiu, Ho-Kuen Ng +2

Let $G = (V (G), E (G))$ be a simple, finite and undirected graph of order $p$ and size $q$ . For $k \geq 1$ , a bijection $f : V (G) \cup E (G) \to {k, k + 1, k + 2, \dots, k + p + q - 1}$ such that…

Cartesian Magicness of 3-Dimensional Boards

Gee-Choon Lau, Ho-Kuen Ng, Wai-Chee Shiu

A $(p, q, r)$ -board that has $pq + p r + q r$ squares consists of a $(p, q)$ -, a $(p, r)$ -, and a $(q, r)$ -rectangle. Let $S$ be the set of the squares. Consider a bijection $f : S \to [1,pq+…
