The local antimagic (total) chromatic numbers of firecracker graphs and edge-corona product graphs

Xue Yang, Hong Bian, Xueliang Li +2

Let G=(V(G),E(G)) be a connected simple graph with n vertices and m edges. A bijection f from the edge set of G to [m] is called a local antimagic labeling of G, if for any two adj…

On Neutral Edge Sets in Anti-Ramsey Numbers

Ali Ghalavand, Qing Jie, Zemin Jin +2

The anti-Ramsey number of a graph , introduced by Erdős et al.\ in 1975, is the maximum number of colors in an edge-coloring of the complete graph that avoids a rainbow co…

On the Anti-Ramsey Number Under Edge Deletion

Ali Ghalavand, Qing Jie, Zemin Jin +2

According to a study by Erdős et al. in 1975, the anti-Ramsey number of a graph \(G\), denoted as \(AR(n, G)\), is defined as the maximum number of colors that can be used in an ed…

On the local metric dimension of -free graphs

Ali Ghalavand, Xueliang Li

Let \( G \) be a graph with order \( n(G) \geq 5 \), local metric dimension \( \dim_l(G) \), and clique number \( ω(G) \). In this paper, we investigate the local metric dimension…
