On the Castelnuovo-Mumford regularity of products of ideal sheaves
Jessica Sidman
In this paper we give bounds on the Castelnuovo-Mumford regularity of products of ideals and ideal sheaves. In particular, we show that the regularity of a product of ideals is bou…

A sharp bound for the Castelnuovo-Mumford regularity of subspace arrangements
Harm Derksen, Jessica Sidman
We show that the ideal of an arrangement of d linear subspaces of projective space is d-regular in the sense of Castelnuovo and Mumford, answering a question of B. Sturmfels. In pa…
