3-uniform hypergraphs: modular decomposition and realization by tournaments

Combinatorics 2018-05-15 v1

Abstract

Let HH be a 3-uniform hypergraph. A tournament TT defined on V(T)=V(H)V(T)=V(H) is a realization of HH if the edges of HH are exactly the 3-element subsets of V(T)V(T) that induce 3-cycles. We characterize the 3-uniform hypergraphs that admit realizations by using a suitable modular decomposition.
