Ideals Associated To Subspace Arrangements

Motivated by the study of the Castelnuovo-Mumford regularity of products of ideals  Herzog and I proved, about twenty years ago,  that a product of ideals of linear forms  has a linear resolution. Only recently Tsakiris and I managed to  describe  such a resolution. It is supported on a polymatroid naturally attached  to the  associated subspace arrangements.
