This ticket implements affine connections on infinitely differentiable manifolds (i.e. smooth manifolds) . This is a follow-up of #19092 within the [SageManifolds project](http://sagemanifolds.obspm…

Instances of `RealSet` that are finite unions of open intervals should be connected in some way to `sage.manifolds`, in particular to `OpenInterval` and `RealLine` (which are both in the global name…

Replacing
* `/\` by ∧ (U+2227)
* `*` by ⊗ (U+2297) for tensor products
* `-->` by → (U+2192), `|-->` by ↦ (U+21A6)
* `d/dx` by ∂/∂x, etc. (U+2202)
* `R` (real field) by ℝ (U+211D)

Internal lists and dictionaries should not be altered by the user. In order to avoid such things, methods should always return a shallow copy.

This ticket introduces periodic coordinates on manifolds for more flexibility.
In particular, this fixes an issue with the azimuthal angle phi being limited to the interval (0,2*pi). For instance, …

**Hi lezcano**
Could you **provide me with some advice** If I want to study the topic of **optimization of manifolds and Euclid** in the long term.
Now, **The only deficiency is I have …

It would be really helpful in Style to be able to say something like
```
scalar x.val = random( minVal, maxVal )
```
and get a random value that stays fixed throughout optimization. This valu…
