D.5.5.11 Delta
Procedure from library resolve.lib (see resolve_lib).
- Usage:
- Delta (BO);
BO = basic object, a list: ideal W,
ideal J,
intvec b,
list Ex,
ideal ab,
intvec v,
intvec w,
matrix M
- Assume:
- R = basering, a polynomial ring, W an ideal of R,
J = ideal containing W
- Compute:
- Delta-operator applied to J in the notation of
[Bravo,Encinas,Villamayor]
- Return:
- ideal
