X-Git-Url: http://gitweb.michael.orlitzky.com/?a=commitdiff_plain;h=723fd0f50c7997768c3d098c707df30197b88afd;hp=723fd0f50c7997768c3d098c707df30197b88afd;p=sage.d.git

eja: fix the natural representation in trivial subalgebras.

The natural representation relies on knowing a matrix space, and in a
trivial subalgebra there ain't no matrices to have no spaces. To work
around that, the space is now computed/stored separately, in a new
natural_basis_space() method. This is then overridden in the subalgebra
class to do the right thing.
