A Twisted sl2(C) Isomonodromic-Isospectral Correspondence
Abstract
The aim of this article is to generalize the isomonodromic-isospectral correspondence for meromorphic connections of rank 2 over P1 to the twisted case. More specifically, the construction of the isospectral approach is provided for the Painlev\'e I hierarchy, then two maps are constructed, one linking the sets of isomonodromic and isospectral Hamiltonians, another linking the set of apparent singularities to a set of isospectral coordinates.
