Jul 15, 2023 at 23:32 comment added Theo Diamantakis I see., thank you. Is there some geometric intuition this can impart or is it just operations that happen to be nice?
Jul 15, 2023 at 21:31 comment added YCor It's not through conjugation, it's through left translation. Yes, all groups acts in this way, but for many groups it's not the "best" action (typically one needs to enlarge, or mod out, to get something contractible). But for Carnot groups, the group itself is the right object.
Jul 15, 2023 at 19:26 comment added Theo Diamantakis I suppose so, but since all groups act on themselves through conjugation that feels a little bit underwhelming.

Jul 15, 2023 at 17:21 comment added YCor I think that "the" nice space on which a Carnot group acts is itself (with a left-invariant CC metric).
