摘要

在连接模空间、单态、Riemann-Hilbert态射和okamoto - painlev空间的背景下，详细研究了第五阶painlev方程${\rm P}_5$的等同构性。这涉及Stokes矩阵和抛物结构的显式公式。由Noumi-Yamada等人引入的${\rm P}_5$的4阶Lax对被证明是由4阶连接的自然精细模空间诱导出来的。作为副产物，我们得到${\rm P}_5$的多项式哈密顿量，等价于冈本的哈密顿量。

Moduli Spaces for the Fifth Painlevé Equation

Isomonodromy for the fifth Painlevé equation ${\rm P}_5$ is studied in detail in the context of certain moduli spaces for connections, monodromy, the Riemann-Hilbert morphism, and Okamoto-Painlevé spaces. This involves explicit formulas for Stokes matrices and parabolic structures. The rank 4 Lax pair for ${\rm P}_5$, introduced by Noumi-Yamada et al., is shown to be induced by a natural fine moduli space of connections of rank 4. As a by-product one obtains a polynomial Hamiltonian for ${\rm P}_5$, equivalent to the one of Okamoto.
