For total degree, I'm using the definition here: http://planetmath.org/encyclopedia/OrderAndDegreeOfPolynomial.html So I am not concerned about individual degrees at all. > Furthermore I am not happy with this implementation in general.

If the value 0 I don't explicitly discard repetitions in 3), the dictionary object takes care of that by discarding repeated keys (in this case, the keys are the degree tuples). didier > gains the same importance as all other values in the corresponding set > of values, than the multiple occurance of 0 is a repetition, too. > > I am quite new in SAGE and have no idea how sage code looks like, but > I will have a look and see if I can do some changes :-) > > Cheers, Steffen > > > > > > > --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://sage.scipy.org/sage/ and http://modular.math.washington.edu/sage/ -~----------~----~----~----~------~----~------~--~---
