| 概要 | The Borcherds Phi-function is the automorphic form on the period domain for
Enriques surfaces characterizing the discriminant locus, which is closely analogous
to the Dedekind eta-function. Originally, it was constructed as the denominator function
of certain infinite dimensional Lie algebra. Some differential geometric constructions of
the Borcherds Phi-function are also known. In this talk, I will report an algebraic construction
of the Borcherds Phi-function. This is a joint work with S. Kawaguchi and S. Mukai. |
