| Jun 4, 2021 at 17:01 | comment | added | Dylan Thurston | that's really a separate question, and not really precise enough for me to answer as stated. | |
| Jun 3, 2021 at 12:17 | comment | added | giulio bullsaver | A related question: there is a map (the shear map) from the decorated teichmuller space to a subspace of the teichmuller space of a surface with holes. The map lands in the subspace of the latter where holes have length 0 (so that they are effectively punctures). Is there a generalization of this map whose image covers all of the target Teichmuller space? | |
| Apr 29, 2021 at 21:33 | comment | added | Dylan Thurston | I would personally love such an interpretation. The Fenchel-Nielsen coordinates have an algebraic structure that looks remarkably similar to the cluster algebra structure, but I don't know how to make it look as neat. It's possible the right point of view is to make a "triangulation" with spun ideal triangles (spinning along the pants curves), | |
