Deligne's functorial Riemann-Roch formula
- Date: 09/13/2007
Lecturer(s):
Damian Roessler (CNRS, Institut de Mathematiques de Jussieu)
Location:
University of British Columbia
Topic:
We shall formulate a refinement, due to Deligne, of the
Riemann-Roch theorem for fibrations of curves. This theorem
provides canonical isomorphisms between certain determinant bundles. We
shall show how this theorem leads to a new construction of the modular
units.
