In the following code the computation seems to run forever, even hitting Ctrl-C doesn't stop that.
k.<b,c> = QQ[] l = k.fraction_field() r.<x> = l[] A = 2*(x^4+x^40)+b*(x^8+x^36)+c*(x^12+x^32) B = A.subs(1/x) If I drop the factor 2* in A=..., then I instantly get the correct result. I'm running Sage 5.10. I know that factorizations of multivariate polynomials always has been a mess in Sage, but I'm surprised to see that even a trivial formal computation doesn't work reliably. -- Peter Mueller -- You received this message because you are subscribed to the Google Groups "sage-support" group.
