Moduli Spaces for Linear Differential Equations and the Painlevé Equations

In this paper, we give a systematic construction of ten isomonodromic families of connections of rank two on P1 inducing Painlevé equations. The classification of ten families is given by considering the Riemann-Hilbert morphism from a moduli space of connections with certain type of regular and irregular singularities to a corresponding catetorical moduli space of analytic data (i.e., ordinary monodromy, Stokes matrices and links), which is called the monodromy space. Explicit equations of the monodromy spaces for ten families are calculated. Moreover, we obtain natural explicit families of connections for these ten cases and calculate isomonodromic equations which give Painlevé equations of all types.
