Let Hodge structure mean pure rational Hodge structure below. Then. The category of polarizable pure Hodge structures is abelian and semisimple (morphisms are not required to respect polarizations). This is essentially proved in Theorie de Hodge II.

WebSep 5, 2024 · The Hodge-Tate comparison gives the Cartier isomorphism when (without the extra Frobenius twist). One can work out the Hodge-Tate comparison explicitly for the -de Rham complex (see notes).
