Comment (by darij):
Thanks for the update. Commenting as I'm reading through it:
Sorry for the trac syntax in the docstrings; that was stupid of me.
I've changed
{{{
This example demonstrates the non-commutativity of
the internal
coproduct::
}}}
into
{{{
This is confirmed by the following Sage computation
(incidentally
demonstrating the non-cocommutativity of the internal
coproduct)::
}}}
In contexts like
{{{
Element methods of the ``Monomial`` basis of ``QuasiSymmetricFunctions.``
}}}
the period should be outside of the verbatim mode.
I added a link to Gessel's paper in the reference list.
Replaced "degree of the power series" by "total degree of the power
series".
"the product by the realization within the polynomial ring" replaced by
"the product on the realization within the ring of power series".
The next paragraph now reads
{{{
There is a coproduct on `\mathrm{QSym}` as well, which in the Monomial
basis acts by cutting the composition into a left half and a right
half. The coproduct is not co-commutative::
}}}
