For the inverse Cole-Hopf transformation, it looks like you are just using `np.exp()`—that doesn't seem right. The initial conditions don't have periodic boundary conditions after transformation, and …

Most of [the tests in #25149](https://github.com/sagemath/sagetrac-mirror/blob/develop/src/sage/tests/combinatorial_hopf_algebras.py?id=5a5f456ebdce848702d6dd0754ec453554b731ef) are currently invali…

Feature request: use Brent's method for bifurcation location. Should be as robust and faster than bisection. There's a julia implementation over at Roots.jl (although the algorithm as described on wik…

Hello,
Here is a beautiful Hopf torus:

The current isotropic initial condition uses `scipy.spatial.transform.Rotation.random` which seems to be constructed by sampling normal distributions in quaternion space (scipy `Rotation`s are impleme…

So I know there was a discussion a while back #573, about moving some files out of HITs to other places. The way I see it, there are only a few "real" HITs that have to be specified with axioms. These…
