comment Weyl group Invariants
Lepanais: If I recall correctly it is the combination of Chevalley's Theorem and the First Fundamental Theorem of Invariant Theory for the Classical groups. Does that help?

comment Why is the half-torus rigid?
I was mentally imagining switching out $\det{h}$ with $K\det{g}$ whenever it created trouble but that doesn't quite get the job done, does it. Just as an idea, perhaps $h_{12}$ can be assumed zero at a single point via a rigid motion, and then controlled via a Gronwall-type inequality regardless of the elliptic/hyperbolic nature of the system, hence leaving only a linear system in the diagonal variables.

Thanks George! So quadruple backslash is the trick.

Any tips on how to get the matrix to go over two lines?
