Koszulness, Krull Dimension and Other Properties of Graph-Related Algebras
Alexandru Constantinescu, Matteo Varbaro
The algebra of basic covers of a graph G, denoted by \A(G), was introduced by Juergen Herzog as a suitable quotient of the vertex cover algebra. In this paper we show that if the g…

On the h-vectors of Cohen-Macaulay Flag Complexes
Alexandru Constantinescu, Matteo Varbaro
Starting from an unpublished conjecture of Kalai and from a conjecture of Eisenbud, Green and Harris, we study several problems relating h-vectors of Cohen-Macaulay, flag simplicia…

Matteo Varbaro
We prove that all the symbolic powers of a Stanley-Reisner ideal are Cohen-Macaulay if and only if the associated simplicial complex is a matroid.
