Hi, I'm using Sage 2.10 now. Expansion for elements in SFAElementary works great now, but there is another problem: the expansion lies in the wrong ring.
sage: e=SFAElementary(QQ) sage: f=e([2]).expand(2) sage: f x0*x1 sage: f.parent() Multivariate Polynomial Ring in x0, x1, x2 over Rational Field The same code but for SFASchur results in: sage: s=SFASchur(QQ) sage: f=s([2]).expand(2) sage: f x0^2 + x0*x1 + x1^2 sage: f.parent() Multivariate Polynomial Ring in x0, x1 over Rational Field Thanks, BFJ On Jan 17, 1:46 pm, "William Stein" <[EMAIL PROTECTED]> wrote: > On Jan 17, 2008 10:44 AM, BFJ <[EMAIL PROTECTED]> wrote: > > > > > Excellent, Thanks.
