I don't understand why you create the _sorting_key
attribute? Why not just use _basis_key
(which is guaranteed to exist from the category)? Nice catch on that bug in _bracket_
, which then with using _basis_key
would become
if key_ml < key_mr: +if self._basis_key(key_ml) < self._basis_key(key_mr):

If I use _basis_key
, I get this:
sage: d = lie_algebras.VirasoroAlgebra(QQ) sage: d._basis_key(3) 3 sage: d._basis_key('c') 'c'
As a result, sorting doesn't work between them in Python 3. The _sorting_key
attribute as I've defined it uses the function _basis_key
in that file, which converts c
to +Infinity
.

I could instead add a new _basis_key
method:
def _basis_key(self, m): return _basis_key(m)

The code in categories/lie_algebras_with_basis.py
already uses self._basis_key(...)
, so I added a _basis_key
method for the Virasoro algebra.
