D.6.12.4 StabEqn
Procedure from library qhmoduli.lib (see qhmoduli_lib).
- Usage:
- StabEqn(f); f polynomial
- Purpose:
- compute the equations of the isometry group of f.
- Assume:
- f semiquasihomogeneous polynomial with an isolated singularity at 0
- Return:
- list of two rings 'S1', 'S2'
- 'S1' contians the equations of the stabilizer (ideal 'stabid')
- 'S2' contains the action of the stabilizer (ideal 'actionid')
- Global:
- varSubsList, contains the index j s.t. x(i) -> x(i)t(j) ...
