An Inductive Approach to Strongly Antimagic Labelings of Graphs

Daphne Der-Fen Liu, Vicente Lossada

An antimagic labeling for a graph $G$ with $m$ edges is a bijection $f : E (G) \to {1, 2, \dots, m}$ so that $ϕ_{f} (u) \neq = ϕ_{f} (v)$ holds for any pair of distinct vertices $u, v \in…

Radio Number for the Cartesian Product of Two Trees

Devsi Bantva, Daphne Der-Fen Liu

Let $G$ be a simple connected graph. For any two vertices $u$ and $v$ , let $d (u, v)$ denote the distance between $u$ and $v$ in $G$ , and let $d iam (G)$ denote the diameter of $G$ . A…

Optimal Radio Labellings of Block Graphs and Line Graphs of Trees

Devsi Bantva, Daphne Der-Fen Liu

A radio labeling of a graph $G$ is a mapping $f$ : $V (G) \to {0, 1, 2, ...}$ such that $∣ f (u) - f (v) ∣ \geq d iam (G) + 1 - d (u, v)$ holds for every pair of vertices $u$ and $v$ …
