[sage-combinat-devel] images on the notebook at sage.lacim.uqam.ca

2012-08-13 Thread Christian Stump
Hi, for the record: I updated sage.lacim.uqam.ca and now, the notebook shows images again properly. I will give a presentation tomorrow at the ICRA computer algebra session (http://www.math.uni-bielefeld.de/icra2012/conference_tuesday.php), so I am glad this issue was solved in 5.2! Best, Chrstia

I think that the default behaviour for categories like GradedAlgebra, GradedAlgebraWithBasis, GradedModule, ... should be to return an error if the element is not homogeneous. I have some code which works with graded modules for a graded algebra and this is what my degree method does -- and is_
