comment Necessary condition for symmetric sums
Yes, precisely! Now the first and the second equation look similar, as they are both "boundaries". Here I don't need something like $\partial^2=0$, the sufficient condition could look very different from the symmetric sum.

The actual field is information geometry, maybe someone will answer.

comment Wedge product of Lie algebra valued differential forms
I assume $T_\alpha T_\beta$ is the usual matrix product, so that you are talking about matrix Lie groups?

comment Fourier transform - epicycles.
The circle is $e^{ix}$. So $\sin x$ is the sum of two "opposite" circles: $(e^{ix}-e^{-ix})/2i$.

comment Is there a deeper meaning when a number is squared?
I'd say that the "squared" in kinetic energy is a matter of modulus. Every time you don't need the direction of the vector, the most natural thing to take is its square modulus. In physics, in probability, in geometry, etc.
