D.15.6.3 multIdeals

Procedure from library hodge.lib (see hodge_lib).

Usage:
multIdeals(f, [, eng]); f a reduced poly, eng an optional integer.

Return:
list

Purpose:
compute the multiplier ideals of a hypersurface $f \in R$.

Note:
The value of eng controls the algorithm used for Groebner basis computations.
See the engine procedure from dmodapp_lib for the available algorithms.

Display:
If printlevel=1, progress debug messages will be printed.

Example:
 
LIB "hodge.lib";
ring R = 0,(x,y),dp;
poly f = y^2-x^3;
multIdeals(f);
