Btw, another there is another issue related to the order of indeterminates described at https://ask.sagemath.org/question/53319/ Regards, Max On Thu, Sep 9, 2021 at 11:01 AM Max Alekseyev wrote: > That would be nice to fix. Btw, there is also the same issue with formal > integration - l

[sage-support] .closest_vector() function is broken

The following code in Sage 9.4 gives me *KeyError? : ((None,), ())* followed by *AttributeError? : 'sage.symbolic.expression.Expression' object has no attribute 'ceil*': from sage.modules.free_module_integ

[sage-support] Re: differentiation in InfinitePolynomialRing

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, 2021

[sage-support] differentiation in InfinitePolynomialRing

I've found a couple of issues with differentiation in InfinitePolynomialRing (ISSUE #1) Differentiation fails in InfinitePolynomialRing(QQ), e.g. the following code R. = InfinitePolynomialRing(QQ) f = x[0] + x[1] derivative(f,x[1]) gives an error TypeError: Argument 'var' has incorrect type (ex

Re: [sage-support] Re: after upgrade to 9.3, SignalError: Illegal instruction

I'm also seeing illegal instruction in Sage 9.3 and 9.4 (and not in 9.2) while doing some linear algebra, although I'm not sure if it's the same bug or not. In either case, my bugreport is submitted to https://trac.sagemath.org/ticket/32447 Regards, Max On Thursday, August 26, 2021 at 2:38:10
