James Borger

I will be away for much of the first half of 2008, visiting the University of Chicago.

Interests:
I work in number theory, algebraic geometry, and related fields. In particular, I'm interested in Lambda-algebraic geometry and (even more particularly) the de Rham cohomology of Witt spaces and the relation to the classical motivic realizations.
