7.7.6.0. lpSickleDim
Procedure from library fpadim.lib (see fpadim_lib).
- Usage:
- lpSickleDim(G[,degbound,n]); G an ideal, degbound, n optional integers
- Return:
- list
- Purpose:
- Computing the K-dimension and the mistletoes
- Assume:
- - basering is a Letterplace ring. G is a Letterplace ideal.
- if you specify a different degree bound degbound,
degbound <= attrib(basering,uptodeg) should hold.
- Note:
- - If L is the list returned, then L[1] is an integer, the K-dimension,
L[2] is an ideal, the mistletoes.
- If degbound is set, there will be a degree bound added. 0 means no
degree bound. Default: attrib(basering,uptodeg).
- n is the number of variables, which can be set to a different number.
Default: attrib(basering, lV).
- If the K-dimension is known to be infinite, a degree bound is needed
