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 $v$ …

Radio-k-Labeling of Cycles for Large k

Colin Bloomfield, Daphne Der-Fen Liu, Jeannette Ramirez

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 $G$ . A radio- $k$ -labeling of $G$ for a fixed positive…
