I cannot possibly estimate the difficulty of this, but it would be great to define a conjugation or adjoint operation over the variables and monomials. The first interesting case is monomials of compl…

Here are some goals we set at the 4/15 meeting:
- "Nearby" function to get a close Toeplitz, Hankel, Cauchy, etc. approximation to a given matrix
- "Norms" fast norm computations for our structure…

`from sympy import Poly`
`from sympy.abc import x`
`f = Poly(x**3 + 2*x - 1, x) `
`f.subs(x, Matrix([1]))`
gives `Poly(Matrix([[1]])**3 + 2*Matrix([[1]]) - 1, Matrix([[1]]), domain='ZZ')`

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…

Currently we have Math::Primality::BigPolynomial, which basically allows you to create univariate polynomials with Math::GMPz objects as coefficients.
Last night I was going to extract BigPolynomial …

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…

Hello AbstractAlgebra folks,
Is this intended behaviour?
```
using Oscar
Qp = PadicField()
I = identity_matrix(QQ, 5)
I[1,1] === I[2,2] # evaluates to false
Ip = identity_matrix(Qp, 5)
Ip[…
