D.6.11.3 jacoblift

Procedure from library mondromy.lib (see mondromy_lib).

Usage:
jacoblift(f); f poly

Assume:
The polynomial f in a series ring (local ordering) defines an isolated hypersurface singularity.

Return:
The procedure returns a list with entries kappa, xi, u of type int, vector, poly such that kappa is minimal with f^kappa in jacob(f), u is a unit, and u*f^kappa=(matrix(jacob(f))*xi)[1,1].

Display:
The procedure displays comments if printlevel>=1.

Example:
