摘要:

本文研究并构建了与任意数量非分歧极点且极点次数任意的$\frak{gl}_2(\frak{C})$亚纯联络相关的哈密顿系统。具体而言,我们提出了用不规则时间、与极点相关的单值性以及在oper规范中定义为表观奇点的$g$个达布坐标表示的Lax对和哈密顿演化。此外,我们还将等单值变形约化为$g$个非平凡等单值变形的子集,该约化等价于将不规则时间集约化为仅$g$个非平凡等单值时间的映射。我们将构造应用于所有相关谱曲线亏格为1的情况,恢复了标准Painlevé方程,并最终从该视角建立了与拓扑递归和经典谱曲线量子化的联系。

英文摘要:

In this paper, we construct the Hamiltonian systems attached to generic $\mathfrak{gl}_2(\mathbb{C})$ meromorphic connections with an arbitrary number of unramified poles of arbitrary orders, under the assumption that every leading polar coefficient is regular semisimple. In particular, we propose the Lax pairs and Hamiltonian evolutions expressed in terms of irregular times and monodromies associated to the poles as well as $g$ pairs of Darboux coordinates defined as the apparent singularities arising in the oper gauge. Moreover, we also provide a reduction of the isomonodromic deformations to a subset of $g$ non-trivial isomonodromic deformations. This reduction is equivalent to a map reducing the set of irregular times to only $g$ non-trivial isomonodromic times. We apply our construction to all genus-one cases covered by these hypotheses and recover the standard Painlevé equations $2$--$6$. We finally make the connection with the topological recursion and the quantization of classical spectral curves from this perspective.
