Deligne's functorial Riemann-Roch formula
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.
