Discriminant of theta divisors and Quillen metrics
Ken-Ichi Yoshikawa
We show that analytic torsion of smooth theta divisor is represented by a Siegel modular form characterizing the Andreotti-Mayer locus if its dimension is positive.

K3 Surfaces with Involution and Analytic Torsion
Ken-Ichi Yoshikawa
This is the abstruct of the revised paper. We study the equivariant analytic torsion for K3 surfaces with an anti-symplectic involution with the invariant lattice M (such a surface…
