| Sep 24, 2021 at 18:49 | comment | added | James Propp | Direct and inverse limits are important concepts but I'm looking for something more flexible that captures some of the latent geometry of the group. Meanwhile ultra limits seem TOO floppy! Maybe I should ask a specific question: Is there a version of what I said above about R/Z (which also works for (R/Z)^n) and applies it to the group of Mobius transformations vis-a-vis its discrete subgroups? | |
