It seems there is quite some inefficient conversion code from OSCAR to Singular (perhaps also the other way around) in e.g. `src/Rings/mpoly.jl`. One example:
```julia
function (SF::Singular.N_AlgEx…

**Describe the bug**
`mapreduce(f, op, ::CuArray)` assumes commutative `op`.
I should've paid more attention in https://github.com/JuliaGPU/CUDA.jl/pull/500 but it didn't solve https://github.co…

Commutative algebra is the study of commutative ring and is a ticket to a lot of modern mathematics. For example, homological algebra, algebraic number theory, algebraic geometry, arithmetic geometry,…

The order that xts objects are passed to `merge.xts` can produce different results when the index classes differ. It seems reasonable to expect that the same result be returned regardless of the orde…

The following code (assuming the operators
