Abstract
In the present paper we discuss the general facts concerning the Schlesinger system: the 7-function, the local factorization of solutions of Fuchsian equations and holomorphic deformations. We introduce the terminology “isoprincipal” for the deformations of Fuchsian equations with general (not necessarily non-resonant) matrix coefficients corresponding to solutions of the Schlesinger system. Every isoprincipal deformation is isomonodromic. The converse is also true in the non-resonant case, but not in general.
In the forthcoming sequel we shall give an explicit description of a class of rational solutions of the Schlesinger system, based on the techniques developed here, and the realization theory for rational matrix functions.
