the function 1/n : AA->AA is 1-1 on all AA, and I don't see why this property should be broken. Mathematically it makes perfect sense as is. In fact, it should also work like this for any real field, not only AA. Dima -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
