Eastern European mathematicians are really all over that higher order G-structure thing

Wait a minute, I think there is a theory if the G-structure is just $e$
That's what teleparallel gravity is

Yeah $\nabla e = 0$ is the compatibility condition for a trivial group I think

What if there is a particle for which can self-interact while violating energy conservation. It would be some like a glider gun in Conways' Game of Life

I just came across this question, which was closed under the site's homework policy. However, I fail to see how it is related to a specific calculation or is "check-my-work-like". While it does refer to a particular sort of expression, it seems to me that it mostly focuses on its physical meaning...
