Koszul binomial edge ideals of pairs of graphs
Herolistra Baskoroputro, Viviana Ene, Cristian Ion
We study the Koszul property of a standard graded -algebra defined by the binomial edge ideal of a pair of graphs . We show that the following statements are equi…

On the Hilbert series of vertex cover algebras of unmixed bipartite graphs
Cristian Ion
We compute the reduced Gröbner basis of the toric ideal with respect to a suitable monomial order and we study the Hilbert series of the vertex cover algebra , where is a…

Cristian Ion
We study the Hilbert function and the Hilbert series of the vertex cover algebra , where is a Cohen-Macaulay bipartite graph.
