Feb 19, 2022 at 18:57 comment added julien lagarde What about this: if rotations are going back and forth between 2D and 3D space, is there a way to estimate the frequency of occurence of non commutative motion?

Feb 11, 2022 at 14:24 comment added dohmatob @julien lagarde It appears what you describe here is the context / motivation of / for your problem. What is missing is the actual math question, stripped of all non-math details. For example, "I wonder if mathematical tools can help quantifying the extent to which those couplings among rotations reduce the non commutativity of human body motion" is not a math question, it's a question about modeling human body motion.

Feb 10, 2022 at 21:49 comment added LSpice I’m voting to close this question because this seems like a fascinating area for exploration, but it seems way too broad to be appropriate as an MO question.
