These consequences are given in terms of intersections with arbitrary linear subspaces. We use our results to bound homological invariants of some well-known projective varieties, to give a combinatorial characterization of quadratic monomial ideals with a long strand of linear syzygies, etc26 pages, Plain TeX + diagrams.texAlgebraic GeometryCommutative AlgebraCombinatorics14N05, 13D02, 14M17text
