When trying to run the following code:
R.<t> = FunctionField(QQ) S.<x, y> = PolynomialRing(R,2) I = S.ideal([x^2 - y^2, y-t]) I.groebner_basis() I receive the following error: AttributeError: 'str' object has no attribute 'parent' After testing the code again with the 'toy:buchberger2" GB algorithm, I found that it was able to do it. Looking into the code it fails when passing into singular and isn't currently handled by the current error exceptions. To me, it seems that all that needs to be done is to add an AttributeError to the except list in the multi_polynomial_ideal grobner basis definiton. However, I have very little knowledge as to how Function Fields are implemented, so I was just wondering if this would be a reliable fix. If not, I was wondering if anyone could help shed some light on what can be done regarding this issue. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
