Rei Inoue, Pol Vanhaecke, Takao Yamazaki
We study the singular iso-level manifold of the genus Mumford system associated to the spectral curve . We show that is stratified by open…

Jacobian variety and Integrable system -- after Mumford, Beauville and Vanhaecke
Rei Inoue, Yukiko Konishi, Takao Yamazaki
Beauville introduced an integrable Hamiltonian system whose general level set is isomorphic to the complement of the theta divisor in the Jacobian of the spectral curve. This can b…

Cohomological study on variants of the Mumford system, and integrability of the Noumi-Yamada system
Rei Inoue, Takao Yamazaki
The purpose of this paper is twofold. The first is to apply the method introduced in the works of Nakayashiki and Smirnov on the Mumford system to its variants. The other is to est…
