Pure Maths Colloquium: Gauss-Manin connection via Witt-differentials
24 January 2005 16:00 in CM221
"Using the relative de Rham-Witt complex we prove an equivalence of categories between the category of locally free crystals on a scheme which is smooth over a p-adic base scheme and the category of de Rham-Witt connections, thereby generalizing a recent result of Bloch. As an application we give a de Rham-Witt realization of the Gauss-Manin connection."
