That would be nice to fix. Btw, there is also the same issue with formal integration - like in the example below: K. = PolynomialRing(QQ) R. = InfinitePolynomialRing(K) f = x[0] + x[1] integrate(f,x[2]) which fails while integrate(f,x[1]) works fine. Regards, Max On Thursday, September 9

ing the actual differentiation to it. I think as a temporary fix for ISSUE#2, one can create an polynomial being a sum of all variables that may ever appear later to make sure that the underlying PolynomialRing knows about them all upfront. Regards, Max On Wednesday, September 8, 2021 at 10:30:21

[sage-support] differentiation in InfinitePolynomialRing

2021-09-08 Thread Max Alekseyev
ame 'derivative(f,x[2])' command again in the same Sage session, it will succeed. So, it appears that if we differentiate with respect to a new variable, which was not accessed before, then differentiation would fail. I hope this is not an intended behavior and can be easily fixed. Than
