The arithmetical rank of the edge ideals of graphs with pairwise disjoint cycles

Margherita Barile, Antonio Macchia

We prove that, for the edge ideal of a graph whose cycles are pairwise vertex-disjoint, the arithmetical rank is bounded above by the sum of the number of cycles and the maximum he…

The poset of proper divisibility

Davide Bolognini, Antonio Macchia, Emanuele Ventura +1

We study the partially ordered set $P (a_{1}, \dots, a_{n})$ of all multidegrees $(b_{1}, \dots, b_{n})$ of monomials $x_{1}^{b_{1}} \dots x_{n}^{b_{n}}$ which properly divide $x_1^{a_1}\cdots x_n^{a…

Cohomological dimension and arithmetical rank of some determinantal ideals

Davide Bolognini, Alessio Caminata, Antonio Macchia +1

Let $M$ be a $(2 \times n)$ non-generic matrix of linear forms in a polynomial ring. For large classes of such matrices, we compute the cohomological dimension (cd) and the arithme…
