On Lyubeznik type invariants
We discuss for an affine variety Y embedded in affine space X two sets of integers attached to Y⊆X via local and de Rham cohomology spectral sequences. We investigate collapse of the spectral sequences, give topological interpretations, study them in small dimension, and consider to what extent one...
