comment Metric tensor of complex numbers & Hamiltonian Mechanics
the $2$ factor comes from the definition of the partial with respect to $\bar{z}$. // These equations are $N$ complex equations, so $2N$ real eqs. I think I saw that once on one of Marsden's books. Let me search...

Ah, I see. But curvature has double derivatives of the metric tensor. In this case $\eta$ is the metric tensor on the nose :) en.wikipedia.org/wiki/Riemann_curvature_tensor

comment 8 periodicity: Clifford clock- Bott periodicity - KO-dimension in noncommutative geometries
Very rich answer indeed! I appreciate specially the reference to Landsman's notes, which I didn't knew.

$1=HappY(Ne^\omega)^{-1}Ye^{ar}$ to be more accurate.
