Vertex cover algebras of unimodular hypergraphs (2007)
Herzog, Jurgen, Hibi, Takayuki, Trung, Ngo Viet
It is proved that all vertex cover algebras of a hypergraph are standard graded if and only if the hypergraph is unimodular. This has interesting consequences on the symbolic powers of monomial...
