We pull many things from Chevie that are hard-coded. We should rather hardcode those ourselves, plus other stuff that is either hard to compute, or easy to hard-code.
We currently think of hard-cod…

Currently, monomials are represented as unboxed vectors of `Int`s. This seems rather inefficient: an unboxed vector stores an offset, a length, and the data is stored byte-per-byte instead of word-per…

I'm working with polynomials. I'm perfectly content to pass real and complex parts separately using the multiplyReal and multiplyComplex functions, so as cheap as I'm sure it is, I'd rather not have a…

I understand that base_ring should mean "one up" in the ring hierarchy. Like here:
```
julia> R, (x, y, z) = PolynomialRing(QQ, ["x", "y", "z"])
(Multivariate Polynomial Ring in x, y, z over Ration…

In Quantum Mechanics one often defines operators in terms of commutators between them and their actions on kets. For example, a linear oscilator could be defined as:
```python
n hbar O = symbols('n …

@MikaelSlevinsky's transform work by first expanding in a tensor product basis, which contains non-polynomial terms, before transforming to a polynomial basis. For example, to compute OPs on the trian…

While `solve_mod` explicitly states
> Each equation must involve only polynomials in 1 or many variables.
it might be helpful to have a test for that particular error with, say, a discrete log th…

Hi!
I have loaded SenderDB from disk to memory, and doing insert operation for a new data (item-label pair) by `SenderDB::insert_or_assign`. `label_byte_count_` in the loaded SenderDB is 7, but the…

bc.. I propose to reverse the order of polynomial coefficients used by polyval
etc. It was changed to the present order for compatibility with Matlab and
SciPy, but I find this convention annoying eve…
