D.5.5.10 CenterBO
Procedure from library resolve.lib (see resolve_lib).
- Usage:
- CenterBO(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:
- the center of the next blow-up of BO in the resolution algorithm
of [Bravo,Encinas,Villamayor]
- Return:
- list l,
l[1]: ideal describing the center
l[2]: intvec w obtained in the process of determining l[1]
l[3]: intvec b obtained in the process of determining l[1]
l[4]: intvec inv obtained in the process of determining l[1]
