One thing we need to really clarify on is how the elementary operations relate to adjacency matrix representations and if all the adjacency matrices representing the same graph have the same eigenvalu…

Some basic math functions are missing generic implementations. Among these are `exp`, `sin`, `cos`, `sinh`, and `cosh`, although likely there are several others that should be included. From this list…

``NMOD_RED`` reduces a single limb modulo some given `n`. It currently calls ``NMOD_RED2`` which reduces a two-limb `(a_hi, a_lo)` integer mod `n`, where `a_hi` must be `< n` (when called for ``NMOD_R…

We can port the code
https://github.com/JuliaApproximation/ApproxFunOrthogonalPolynomials.jl/blob/master/src/roots.jl
I think call it `findall(iszero,f)`.

Added `matching_generating_poly`, modified `matching_polynomial`, added an option
to `permanental_minor_polynomial`, which for some graphs is faster than the previous
algorithm.
`matching_generatin…

Suppose we form a simple tropical polynomial in the following way:
```
using Oscar
Qt, t = rational_function_field(QQ, "t")
nu = tropical_semiring_map(Qt, t)
Qtx, (x,) = polynomial_ring(Qt, […

I would love to use MagmaCall to ship 100x100 matrices with polynomial coefficients to Magma, compute their nullspace, and pull them back. First step is to send polynomials to Magma, and I see very st…

I figured that someone should probably start some location with a collection of topics that we might want to cover during the review sessions (Thursdays from 6:30-9:15pm).
Personally, I would like i…

https://en.wikipedia.org/wiki/Ray_transfer_matrix_analysis is a good start. However, it only captures radial symmetry. Electron optics are generally not symmetric. The following properties are desirab…

This issue is based on the discussion initiated in [this Discourse thread](https://discourse.julialang.org/t/gathering-monomial-coefficients-of-orthogonal-polynomials-using-specialpolynomials-jl/)
