The Hilbert Scheme of Buchsbaum space curves
Jan O. Kleppe (2012)
Annales de l’institut Fourier
Similarity:
We consider the Hilbert scheme of space curves with homogeneous ideal and Rao module . By taking suitable generizations (deformations to a more general curve) of , we simplify the minimal free resolution of by e.g making consecutive free summands (ghost-terms) disappear in a free resolution of . Using this for Buchsbaum curves of diameter one ( for only one ), we establish a one-to-one correspondence between the set of irreducible components of that contain and a...

On the Hilbert function of curvilinear zero-dimensional subschemes of projective spaces

Similarity:
Here we show the existence of strong restrictions for the Hilbert function of zerodimensional curvilinear subschemes of P n with one point as support and with high regularity index.
