Sum index and difference index of graphs

Joshua Harrington, Eugene Henninger-Voss, Kedjar Karhadkar +2

Let $G$ be a nonempty simple graph with a vertex set $V (G)$ and an edge set $E (G)$ . For every injective vertex labeling $f : V (G) \to Z$ , there are two induced edge labelings,…

On the Domination Number of Permutation Graphs and an Application to Strong Fixed Points

Theresa Baren, Michael Cory, Mia Friedberg +6

A permutation graph $G_{π}$ is a simple graph with vertices corresponding to the elements of $π$ and an edge between $i$ and $j$ when $i$ and $j$ are inverted in $π$ . A set of vertic…
