To establish this bound, we introduce a new combinatorial tool, called a Stanley filtration, for studying monomial ideals in the homogeneous coordinate ring of X. As a special case, we obtain a new proof of Gotzmann's regularity theorem. We also discuss applications of this bound to the construction of multigraded Hilbert schemes.23 pages, 2 figuresAlgebraic GeometryCommutative AlgebraCombinatorics14M25; 14Q20; 13P10text
