Antimagic and product antimagic graphs with pendant edges

Mercè Mora, Joaquín Tey

Let $G = (V, E)$ be a simple graph of size $m$ and $L$ a set of $m$ distinct real numbers. An $L$ -labeling of $G$ is a bijection $ϕ : E \to L$ . We say that $ϕ$ is an antimagic…

Trees whose even-degree vertices induce a path are antimagic

Antoni Lozano, Mercè Mora, Carlos Seara +1

An antimagic labeling a connected graph $G$ is a bijection from the set of edges $E (G)$ to ${1, 2, \dots, ∣ E (G) ∣}$ such that all vertex sums are pairwise distinct, where the vertex…

Caterpillars are Antimagic

Antoni Lozano, Mercè Mora, Carlos Seara +1

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