I also feel like someone who works a lot with mapping class groups should be able to figure out the answer, if they were sufficiently motivated. As I said, we shifted to looking at a slightly different problem, and the motiviation went away. (BTW, I'm talking about a project which led to this paper: arxiv.org/abs/1903.01916) | |
