Infectious power domination of hypergraphs

Combinatorics 2019-10-09 v1

Abstract

The power domination problem seeks to find the placement of the minimum number of sensors needed to monitor an electric power network. We generalize the power domination problem to hypergraphs using the infection rule from Bergen et al: given an initial set of observed vertices, S0S_0, a set AS0A\subseteq S_0 may infect an edge ee if AeA\subseteq e and for any unobserved vertex vv, if A{v}A\cup \{v\} is contained in an edge, then vev\in e. We combine a domination step with this infection rule to create \emph{infectious power domination}. We compare this new parameter to the previous generalization by Chang and Roussel. We provide general bounds and determine the impact of some hypergraph operations.
