Resumen de Grothendieck-Riemann-Roch and the moduli of Enriques surfaces

Georgios Pappas

• We give a short and ``classical" proof of Borcherds' theorem that the moduli space of Enriques surfaces is quasi-affine. The use of the Borcherds' product is replaced in our proof by an application of the Grothendieck-Riemann-Roch theorem
