Niche hypergraphs of products of digraphs
Martin Sonntag, Hanns‐Martin Teichert · Discussiones Mathematicae Graph Theory · 2018
Niche hypergraphs generalize the well-known niche graphs and are closely related to competition hypergraphs as well as common enemy hypergraphs. For several products D 1 D 2 of digraphs D 1 and D 2 , we investigate the relations between the niche hypergraphs of the factors D 1 , D 2 and the niche hypergraph of their product D 1 D 2 .
