一些希钦哈密顿量的等单点变形解释

An Interpretation of Some Hitchin Hamiltonians In Terms of Isomonodromic Deformation

Michael Lennox Wong

摘要:

本文研究了紧致Riemann曲面上具有非正则奇点联络的框架主丛的模空间。这些空间已建成Boalch通过一个无限维辛减少。证明了由Atiyah-Bott形式导出的辛结构与由超上同调给出的辛结构一致。本文的主要结果适应工作的Krichever和Hurtubise给出一个解释的一些希钦哈密尔顿作为产生哈密尔顿向量场的模空间的不规则连接所产生的差异的isomonodromic流定义在两种不同的方式。这依赖于实现开放集的模空间的丛所产生的Hecke修改的固定丛。

英文摘要:

This paper deals with moduli spaces of framed principal bundles with connections with irregular singularities over a compact Riemann surface. These spaces have been constructed by Boalch by means of an infinite-dimensional symplectic reduction. It is proved that the symplectic structure induced from the Atiyah--Bott form agrees with the one given in terms of hypercohomology. The main results of this paper adapt work of Krichever and of Hurtubise to give an interpretation of some Hitchin Hamiltonians as yielding Hamiltonian vector fields on moduli spaces of irregular connections that arise from differences of isomonodromic flows defined in two different ways. This relies on a realization of open sets in the moduli space of bundles as arising via Hecke modification of a fixed bundle.
