Elliptic KZB connections via universal vector extensions

Tiago J. Fonseca, Nils Matthes

Using the formalism of bar complexes and their relative versions, we give a new, purely algebraic, construction of the so-called universal elliptic KZB connection in arbitrary leve…

A note on the Gauss-Manin connection for abelian schemes

Tiago J. Fonseca, Nils Matthes

We study differential forms on the universal vector extension of an abelian scheme in characteristic zero, and derive a new construction of the -group scheme st…
