Lyubeznik numbers of projective schemes
Let be a projective scheme over a field and let be the local ring
at the vertex of the affine cone of under some embedding
. We prove that, when , the Lyubeznik
numbers are intrinsic numerical invariants of , i.e.,
depend only on , but not on the embedding.Comment: revised version, exposition improved, to appear in Advances in
