We get a "solution" from `solve()` that isn't actually a solution:
```
sage: f(x) = (sin(x) - 8*cos(x)*sin(x))*(sin(x)^2 + cos(x)) - (2*cos(x)*sin(x) - sin(x))*(-2*sin(x)^2 + 2*cos(x)^2 - cos(x))

Hello Severin, I do a research in the polynomial embedded system, I want to ask you can this program calculate the Groebner Basis in rational number field rather than finite field, such as Z_{32003}?.…

`groebner_basis` has an option `complete_reduction`, which if set to `true` ensures that the returned Groebner basis is reduced.
Can we equip `reduce` with the same option? The default would be …

**Describe the bug**
`normal_form` sometimes throws this error

The issue is about an integral having two linear propagators
.
Here the momenta are Euclidean, and are orthogonal vectors , the dimension is , and the prescription is implicit. The analytic r…

A `noexcept` function should not call any function that could raise an exception. This includes any python function. As you see below, there are 572 cases of this. PR #37792 fixes one :f…

I think the issue is best described by the following two examples:
When using variables with a designated monomial order, Gröbner basis computations seem to fail, sometimes (the failure isn't rando…

Presently, #715 + #11521 help not permanently keeping parent in memory. In the process we uncovered a hard-but-consistently triggerable problem with the collection of `MPolynomialRing_libsingular`. …

**Describe the bug**
I am not yet sure whether this is a bug, but in the example below the
two computed Gröbner bases are not considered equal despite the
fact that there elements are pairwise equa…

I tried to run the following code:
```
Knn. = PolynomialRing(GF(3), 2)
print(type(Knn))
ts = [t1,t2]
li = [ts[i]^9 - ts[i] for i in range(2)]
I = ideal(li)
print((t1^3 - t2^2).reduce(I)…
