Hail,
Has fail to build on opensuse 11.2 been resolved satisfactorily?
If not, I should bump investigation of this up on my todo list;
although I may wait for another milestone of openesuse 11.3
before investing much effort into a moving target.

Thanks for *not* complaining about the "multiplicative" in "Torsion
Subgroup isomorphic to Multiplicative Abelian Group..."
I once wrote a patch to fix that but no-one liked it enough.
I also tried E.change_ring(QQbar).torsion_subgroup() but that failed
for a different reason! For some reason, E

I think you'll have to do that by manually assigning edge colors.
Here's an example. If you

Ok! I find it!
It is a brutal method but works!!:
singular.lib('decodegb')
singular.lib('matrix.lib')
singular.eval('ring r=11,(x(1..17)),dp;')
singular.eval('list pointok;')
lung=len(provv[1])
for a in provv:
tmp=''
tmp2=''
for j in range(0,lung):
if(j!=0):
tmp=tmp

Hi,
I want to plot weighted graphs such that the link-width or color may

Does this work?
sage: g=DiGraph(random_matrix(ZZ,5))
sage: g.weighted_adjac

Hi!
I try, and I can call vanishid...but there is an other problem..i have
a list of lists (provv), in sage, and i have to conver it into a list
of column vector (for vanishId function).
I try with this code but doesn't work:
singular.lib('decodegb')
singular.lib('matrix.lib')
singular.eval('ring
