| Mar 8, 2010 at 0:57 | comment | added | Tim Perutz | @Somnath. Gromov's theorem implies that every symplectic CP^2-bundle over the 3-sphere is trivial - not just smoothly, but even as a symplectic fibration... | |
| Mar 8, 2010 at 0:38 | comment | added | Somnath Basu | Tim - Gromov proved that $\textrm{Symp}(\mathbb{CP}^2,\omega_{FS})$ is homotopy equivalent to $PU(3)$. May be one can use this instead of $\textrm{Diff}(\mathbb{CP}^2)$? | |
