There are a number of tests `... is SR` in the Sage library, as found by `git grep 'is SR' src/sage/`
These tests ignore symbolic subrings, as constructed by `SR.subring(...)`.
All or most of thes…

In certain cases, when trying to solve singular linear systems, no feedback is given about the singular nature of the solution. For example:
```
>>> import numpy
>>> from numpy import array
>>> from …

Hi there,
I am using SOS optimization to solve an adaptive control problem using the inverse Lyapunov method. I have been successful in obtaining the Lyapunov function and region of attraction leve…

Hi,
I am trying to obtain a candidate Lyapunov function for a dynamical system.
However in the state dynamics I have trigonometric functions such as sin and cos.
I wonder whether it is possible to…

With not heigh knowledge of python class programming I tried to edit file _jitcode.py to be able to solve large system of ODE. Before that I tried simple example of 3 dimensional Roessler system. And …

```julia
N = 200
dlyap(randn(N,N), Matrix(I(N)))
```
crashes julia (on my machine) due to the naive implementation of the Lyapunov solver that attempts to invert N^2 x N^2 matrices.
`covar` and…

### Describe the bug
Running the following snippet on x84_64 is fine, but causes "schur decomposition solver error" in aarch64:
```python
import pmdarima as pm
import numpy as np
model = pm.a…

It would be nice to reuse the same code as in the Mila website. Not sure if that's 'easily' possible via RTD

Goal
To solve sum-of-squares programming through `MathematicalProgram`. The user can write the code like
```C++
// Find the Lyapunov function V(x) for system
// xdot0 = -x1 + 3/2*x0^2 - 1/2*x0^3…
