Heisenberg族的拟周期解

Quasi-periodic solutions of the Heisenberg hierarchy

Xianguo Geng, Zhu Li, Liang Guan

摘要:

利用零曲率方程和迹恒等式分别导出了Heisenberg族和它的Hamilton结构。借助于Lax矩阵,我们引入了算术亏格$n$的代数曲线$\mathcal{K}_{n}$,由此定义了亚纯函数$ϕ$,并在Abel-Jacobi坐标下理顺了Heisenberg族的所有流.最后,利用$ϕ$的渐近性质,得到了整个Heisenberg族解的显式theta函数表示.

英文摘要:

The Heisenberg hierarchy and its Hamiltonian structure are derived respectively by virtue of the zero curvature equation and the trace identity. With the help of the Lax matrix we introduce an algebraic curve $\mathcal{K}_{n}$ of arithmetic genus $n$, from which we define meromorphic function $ϕ$ and straighten out all of the flows associated with the Heisenberg hierarchy under the Abel-Jacobi coordinates. Finally, we achieve the explicit theta function representations of solutions for the whole Heisenberg hierarchy as a result of the asymptotic properties of $ϕ$.
