Good question. It's a bit long, but has some desirable features
besides consistency with realizations/bases:
- The ground field is specified
- It refers to Sym, in such a way that if Sym is renamed to something
short, this gets shorter as well
Btw 1: it would be good to have t specified in the name of the
kBoundedSubspace.
{{{
sage: Sym.kBoundedSubspace(3)
3-bounded Subspace of Symmetric Functions over Fraction Field of
Univariate Polynomial Ring in t over Rational Field
sage: Sym.kBoundedSubspace(3,1)
3-bounded Subspace of Symmetric Functions over Fraction Field of
Univariate Polynomial Ring in t over Rational Field with t = 1
}}}
Btw 2: in the docstrings of new_kschur, wouldn't we want to change
{{{
sage: KBoundedSubspace(Sym,3,1)
}}}
to
{{{
sage: Sym.kBoundedSubspace(3,1)
}}}
(except probably once in the __init__, for testing purposes)?
I am not sure I'll have the time to implement that before Tuesday, so
feel free to beat me to it.
Cheers,
Nicolas
