Deligne's functorial Riemann-Roch formula

  • Date: 09/13/2007

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.
