Reusing variable names is generally a recipe for confusion: R.<x1,x2>=PowerSeriesRing(SR) P.<x1,x2>=PolynomialRing(QQ)
Now R and P have variables that print as "x1" and "x2", but of course they are still different variables. Now compare sage: f x1*x2 + O(x1, x2)^3 sage: f[2] # the degree-2 part in the power series variables x1*x2 sage: f2 x1*x2 + O(x1, x2)^3 sage: f2[0] # the degree-0 part in the power series variables x1*x2 -- You received this message because you are subscribed to the Google Groups "sage-support" group.
