[sage-support] newbie working (again) in polynomial quotient rings

2010-12-07 Thread eggartmumie
Hi, (sorry I was interrupted) I am a SAGE newbie working in polynomial quotient rings: I want to implement the Patterson algorithm to decode Goppa Codes. Therefore, I need to split a polynomial p in a quotient ring in its even part p0 and its odd part p1 such that p(z) = p0^2(z)+z*p1^2(z) = (p0(z))
