Thanks for providing the example, I even forgot about the bug for a while (since I switched back to my old editor). Yes, that replicates the bug and occurs often...

Thanks for the fast answer. Can you see, which packages are used for typesetting? I know either Shaded nor Highlighting as environments. The above examples are for use with `listings`,...

Ah from the paper draft docker file it seems it might use `listings` actually; then the above commands (linked) should work, too :) https://github.com/openjournals/whedon/blob/919a44c1cae3a44f4475db2cd3bbc17b3b3ff721/paperdraft.Dockerfile#L23 edit but the latex template is...

jlcode is indeed not available in can als also a little preliminary (I just added a few symbols back then), and the symbols are also only required for (pdf)latex, since...

Wow, you tackle all the points :) The retraction topic might be a little difficult, since there especially is not _the_ retraction, but you can phrase many operations on manifolds...

> This is motivated by the fact that optimization algorithms are not very sensitive to the choice of retraction Uh, they are. I just spent 2 hours today with a...

I actually mean two retractions, both well-defined and such. So for example on the Sphere, you have * exp (using sine and cosine following great arcs) – yes that _is_...

Mathematically you should always use the exponential map, since the retraction only approximates (up to first order) the correct way to “step in direction X” on a manifold. Retractions (as...

Mathematically, if you are close enough to the minimiser, the retraction acts as good as the exponential map, sure. Maybe my statement was too strong there.

Levi-Cevita, well it is the only torsion free connection that preserves the metric. In the sense of properties it is the best connection. So it is not just a choice,...
