Upper bounds on the $k$ -isolation number

Peter Borg, Magdalena Lemańska, Mercè Mora +1

The isolation number of a graph $G$ (also called the vertex-edge domination number of $G$ ), denoted by $ι (G)$ , is the size of a smallest subset $D$ of the vertex set $V (G)$ of $G$ …

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…
