Sage hangs on the following input: sage: K.<p,d,e,N> = FractionField(PolynomialRing(QQ,4,'pdeN')) sage: R.<x> = K[] sage: a = x-x^-1 sage: b = x^6-x^-6 sage: c = x^7-x^-7 sage: X = p*a + d*b + e*c sage: F = N*a*b*c - X^2*(x-x^-1)
and also on this closely related input sage: K.<p,d,e,N> = FractionField(PolynomialRing(QQ,4,'pdeN')) sage: R.<x>= K[] sage: a = x-x^-1 sage: b = x^6-x^-6 sage: c = x^7-x^-7 sage: X = p*a + d*b + e*c sage: F = N*a*b*c sage: G = X^2*(x-x^-1) sage: F = F-G but if the last line is changed to sage: F = R(x^15*F) - R(x^15*G) then it works fine. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
