Résumé - Abstract

A systematic construction of isomonodromic families of connections of rank two on the Riemann sphere is obtained by considering the analytic Riemann–Hilbert map $RH:\mathcal{M} \rightarrow \mathcal{R}$, where $\mathcal{M}$ is a moduli space of connections and $\mathcal{R}$, the monodromy space, is a moduli space for analytic data (i.e., ordinary monodromy, Stokes matrices and links). The assumption that the fibres of $RH$ (i.e., the isomonodromic families) have dimension one, leads to ten moduli spaces $\mathcal{M}$. The induced Painlevé equations are computed explicitly. Except for the Painlevé VI case, these families have irregular singularities. The analytic classification of irregular singularities yields explicit spaces $\mathcal{R}$, which are families of affine cubic surfaces, related to Okamoto–Painlevé pairs. A weak and a strong form of the Riemann–Hilbert problem is treated. Our paper extends the fundamental work of Jimbo–Miwa–Ueno and is related to recent work on Painlevé equations.
