See original ticket below. We can still use this as a meta-ticket for tracking all division-related changes needed for Python 3. Existing tickets include:

We define a subclass of `ManifoldSubset` whose instances represents the topological closure of given subset in the manifold.
Subsets provide a method `closure` to construct it. When the subset is…

In order to avoid confusion between `_element_constructor_` (a public interface) and `_element_constructor` (a private attribute), we change the latter from `cdef public` to `cdef`. The same for `_e…

In #11900, some regressions were fixed that have been introduced in #9138. It seems that one of the examples from #11900 shows a regression again:
```
sage: E = J0(46).endomorphism_ring()
sage: %ti…

According to the [overview page of the Darts problem](https://exercism.org/tracks/c/exercises/darts), the radius of the concentric circles are defined as:
> The outer circle has a radius of 10 unit…

This is the implementation of manifolds resulting from the [SageManifolds project](http://sagemanifolds.obspm.fr/), developed by the following [authors](http://sagemanifolds.obspm.fr/authors.html). …

### Steps to reproduce
1. open heatmap official examples : https://echarts.apache.org/examples/zh/editor.html?c=heatmap-large
2. set xAxis type to time
3. set corresponding da…

Create classes for the different symmetry classes of plane partitions (Cyclically symmetric, Totally Symmetric, etc.), along with methods taking elements in these symmetry classes to an object in a …

Similar to #31653, given a continuous map `\Phi: N -> M` and a manifold subset `S` of `M`, we define the pullback (preimage) of `S` as the subset of `N` of points `p` with `\Phi(p)` in `S`.
Given a…

This ticket implements the basics of symplectic structures,
like Poisson brackets and Hamiltonian vector fields.
TODO (as follow-up tickets):
- Extract general coordinate stuff from `EuclideanSpace…
