Hi,
The categorification of the crystal code is almost done in
patch trac_8911_categorification_crystals-as.patch .
There are just a few question I have:
* In line 605 and 625 of /categories/crystals.py, how
can I access the method of the category for testing rather
than the one by the class

I finished the use of the category framework for crystals. It is

Hello Everybody
I was working on a function is_perfect, which tests whether a given graph is
perfect. This function has the bad idea to compute the complement of a
graph.
Writing the docstrings, I wrote that Bipartite Graphs are obviously perfect,
which is perfectly true.
Here is what happens
Some years ago I started writing a z-transform routine for Maxima,
based on the following work for REDUCE:

implement rule-based programs. Can anybody provide me with a
Maybe the problem is that somewhere in the depths of is_perfect, a
BipartiteGraph is being created without the intention to use it that
way. Perhaps it is in self.complement(), or some other function that
is implicitly assuming to use the current class to make a copy, when
it should be making a

Nonon, it is just that if you now type g.complement() on a Bipartite

when I call it on a bipartite Graph !
I guess my point is that a graph should be a BipartiteGraph when it
makes sense. It certainly seems right to me to have
