Hello:
I am working with a quantum analogue of the grassmanian algebra G(2,4). It
is a noetherian algebra (of infinite dimension over the field) presented as
a quotient of a free algebra on 6 generators.
I was wondering if anyone has worked in a similar context and can give a
starting point. I
That's awesome, thanks a lot, William!
Since this is done in the units package already, is there a way to
formally save the units of e.g. T_a as units.temperature.Kelvin and then
have something like:
sage: T_a = 300
sage: T_a
300 Kelvin
Cheers

Hi!
Until today, I thought that introspection via ? uses sage_getdoc. I
stand corrected. Apparently it just uses _sage_getdoc_unformatted.
While sage_getdoc is supposed to remove the embedding information,
introspection with ? and _sage_getdoc_unformatted show the embedding
information:

Found it, found it!!
It seems that ? is implemented in sage.misc.sagedoc.my_getdoc.
Looking at the code, it *is* intended to use
sage.misc.sageinspect.sage_getdoc. However, if the object has a
_sage_doc_ method, then its output will be printed without any
formatting applied.

actually, I won't mind having the functionality directly in Sage, at all :)
To be uselful fo rme, it certainly will need to support algebras of
dimension more than, say, 10,000, which
is not so uncommon in my applications (one often get these as centralisers
of permutation
groups, say). This

It is #11817, and ready for review.
It also fixes a fact in sage.misc.sagedoc.format, that ironically is
responsible for the fact that sage.misc.sagedoc.format? did not show
the docstring.

In my case, sometimes keeping multiplication coefficients, even in a sparse
form, is less efficient than recomputing them over and over again, from a
set of sparse matrix generators.

Hi Jonathan,
In theory this could be added to the javascript functions being
included with the update to the Jmol interface which is coming with
the switch to the new flask notebook, but I'm not sure this is the
best solution.
Apparently, people are also interested by the converse [1].
