Caterpillars Have Antimagic Orientations

Antoni Lozano

An antimagic labeling of a directed graph $D$ with $m$ arcs is a bijection from the set of arcs of $D$ to ${1, \dots, m}$ such that all oriented vertex sums of vertices in $D$ are…

Antimagic Labelings of Caterpillars

Antoni Lozano, Mercè Mora, Carlos Seara

A $k$ -antimagic labeling of a graph $G$ is an injection from $E (G)$ to ${1, 2, \dots, ∣ E (G) ∣ + k}$ such that all vertex sums are pairwise distinct, where the vertex sum at vertex $u$ …

Distinguishing Tournaments with Small Label Classes

Antoni Lozano

A $d$ -distinguishing vertex (arc) labeling of a digraph is a vertex (arc) labeling using $d$ labels that is not preserved by any nontrivial automorphism. Let $ρ (T)$ ( $ρ^{'} (T)$ ) be th…
