Euler characteristics of theta divisors of Jacobians for spectral curves
A. Nakayashiki, F. Smirnov
We show how to calculate the Euler characteristic of an affine Jacobi variety of a spectral curve from its defining equations.

On the Cohomology of Theta Divisors of Hyperelliptic Jacobians
Atsushi Nakayashiki
We prove that k-th singular cohomology group of the complement of the theta divisor in a hyperelliptic Jacobian is isomorphic to the k-th fundamental representation of the symplect…
