[edit] Error in n=1 formula?

In the formula

\frac{dz \; d\overline{z}} {\left(1+z^2\right)\left(1+\overline{z}^2\right)} = \frac{dx^2+dy^2}{ \left(1+r^2\right)^2 }

shouldn't the denominator on the left be (1 + z \bar z)^2? Then it matches up with the one on the right, which is correct, I think. Joshua R. Davis 01:17, 3 May 2007 (UTC)

[edit] Separate articles?

I suggest creating a separate article for the "Articulation" section, which discusses the Fubini-Study metric in quantum mechanics. For a math article, all the discussion with bra/ket notation seems out of place. Also, much more should be written on the math side, including how the Fubini-Study metric arises as a submersion of the 2n+1 sphere, its sectional curvatures, etc. Jjauregui (talk) 19:25, 14 April 2008 (UTC)
