Anupper dominating set in a graph is a minimal dominating set of maximum cardinality. The problem of finding an upper dominating set is generally NP-hard.We study the complexity of this problem in finitely defined classes of graphs and conjecture that the problem admits a complexity dichotomy in this family. A helpful tool to study the complexity of an algorithmic problem is the notion of...

An induced matching 𝑀 in a graph 𝐺 is dominating if every edge not in 𝑀 shares exactly one vertex with an edge in 𝑀. The DOMINATING INDUCED MATCHING problem (also known as EFFICIENT EDGE DOMINATION) asks whether a graph 𝐺 contains a dominating induced matching. This problem is generally NP-complete, but polynomial-time solvable for graphs with some special properties. In...
