Abstract

We discuss for an affine variety YY embedded in affine space XX two sets of integers attached to YXY\subseteq X via local and de Rham cohomology spectral sequences. We give topological interpretations, study them in small dimension, and investigate to what extent one can attach them to projective varieties.
