Moduli Spaces for Space Curve Singularities

Tasks: Given the presentation matrix of a quasihomogeneous space curve singularity,

  • find a versal family of semiquasihomogeneous singularities with this fixed initial part,

  • compute the kernel L of the Kodaira-Spencer map of this family,

  • compute the stratification of the base space of the versal family w.r.t. the Hilbert function of T1 and the invariants obtained from the central series of L.
