WebIn particular, Dwork’s work gives a construction of modules isomorphic to the middle (relative) deRham cohomology, equipped with an integrable connection which is equivalent to the Gauss-Manin connection. By the work of Katz and Oda [21], we know that this connection is essentially differentiation of cohomology classes with respect to the ...
