| Nov 1, 2019 at 22:57 | comment | added | Nicolas Hemelsoet | Typo : the sheaves $h^* \Omega^{X/ \Bbb C}$ and $\Omega_{X_{an}}$ are not isomorphic (but the global sections are). Also, if you write $H^k(X, F) = Ext^k(\mathcal O_X, F) = Hom_{D^b(X)}(\mathcal O_X, F[k])$ then you get a product using composition of morphisms in $D^b(X)$. However I don't know a reference and I don't know how to prove that this product is the same as the one obtained from Cech cohomology. | |
