I agree that the valuation for polynomials is confusing. Presently, P.valuation() and P.degree() are the same for non-zero polynomials. If defined at all, P.valuation() should be "the valuation at the infinite place", which would be -P.degree() for non-zero P. The place at infinity is indeed the only one that stands out for a polynomial ring. --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to [email protected] 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/ -~----------~----~----~----~------~----~------~--~---
