Counting perfect edge dominating sets: extremal results and linear-time algorithms

Luciano N. Grippo, Min Chih Lin, Verónica Moyano +1

An edge of a graph \emph{dominates} itself and each edge adjacent to it. A \emph{perfect edge dominating set} is a subset of edges such that each edge outside the subset is dominat…

On the rank of the distance matrix of graphs

Ezequiel Dratman, Luciano N. Grippo, Verónica Moyano +1

Let $G$ be a connected graph with $V (G) = {v_{1}, \dots, v_{n}}$ . The $(i, j)$ -entry of the distance matrix $D (G)$ of $G$ is the distance between $v_{i}$ and $v_{j}$ . In this article, using…
