7.7.6.0. ivSickleDim
Procedure from library fpadim.lib (see fpadim_lib).
- Usage:
- ivSickleDim(L,n[,degbound]); L a list of intmats, n an integer, degbound
an optional integer
- Return:
- list
- Purpose:
- Computing mistletoes and the K-dimension
- Assume:
- - basering is a Letterplace ring.
- all rows of each intmat correspond to a Letterplace monomial
as explained in the overview
- 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, L[2] is a list,
containing the mistletoes as intvecs.
- If degbound is set, a degree bound will be added. By default there
is no degree bound.
- n is the number of variables.
- If the K-dimension is known to be infinite, a degree bound is needed
