Can you clarify? Sage had and used "dedicated and consistent algebraic structures" for polynomial manipulation for many years before Pynac even existed. > Pynac nowaday is mostly calculus.

I think I agree with you. The argument "Pynac is mostly for calculus" is sufficient. It's designed entirely with characteristic 0 calculus in mind... > > Regards, > > -- > You received this message because you are subscribed to the Google Groups > "sage-devel" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to sage-devel+unsubscr...@googlegroups.com. > To post to this group, send email to sage-devel@googlegroups.com. > Visit this group at https://groups.google.com/group/sage-devel. > For more options, visit https://groups.google.com/d/optout. -- William (http://wstein.org) -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
