I'm trying to draw a chain of arrows going under and above each other, as depicted:
The issue isn't labelling the arrows, I can easily do that, but I don't know how to get them to curl, have the arrow head in the middle (ideally, though not necessary), and have one on top of the other. Any help is appreciated. If a solution exists without TikZ, I would prefer it.
For those interested, the above is an eigenvector of the Cartan generators of a Lie algebra acting on a state as a raising or lowering operator, used in the roots and weights method to classify all semi-simple compact Lie algebras.
