 Jan11 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... Jan11 revised Metric tensor of complex numbers & Hamiltonian Mechanics added info Jan11 comment Metric tensor of complex numbers & Hamiltonian Mechanics 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 Jan11 comment Metric tensor of complex numbers & Hamiltonian Mechanics @AimForClarity I'm not sure I understand why you write "curvature" for $\eta$. I do not understand that part of the question.
