On the dimension of the minimal vertex covers semigroup ring of an unmixed bipartite graph
Cristina Bertone, Vincenzo Micale
In a paper in 2008, Herzog, Hibi and Ohsugi introduced and studied the semigroup ring associated to the set of minimal vertex covers of an unmixed bipartite graph. In this paper we…

The Euler characteristic as a polynomial in the Chern classes
Cristina Bertone
In this paper we obtain some explicit expressions for the Euler characteristic of a rank n coherent sheaf F on P^N and of its twists F(t) as polynomials in the Chern classes c_i(F)…

Splitting type, global sections and Chern classes for torsion free sheaves on P^N
Cristina Bertone, Margherita Roggero
In this paper we compare a torsion free sheaf $\FF$ on $\PP^N$ and the free vector bundle $\oplus_{i=1}^n\OPN(b_i)$ having same rank and splitting type. We show that the first one…
