摘要
After reviewing the notion of Castelnuovo-Mumford regularity of a finitely generated graded module over a polynomial ring with coefficients in a field, some history and known results will be discussed regarding the regularity of ideals associated to subspace arrangements and the connections with their Hilbert functions. In the sequel, recent results obtained together with Aldo Conca will be presented, which improve the bound of Derksen & Sidman (2002) for arrangements in projective space of generic linear spaces of codimension at least 2.
