Abstract:

In this paper, we will show that the Hesselink stratification of a Hilbert scheme of hypersurfaces is independent of the choice of Plücker coordinate and there is a positive relation between the length of Hesselink’s worst virtual 1-parameter subgroup and multiplicity of a projective hypersurface.
