Abstract: We consider the problem of confluence of singular points under isomonodromic deformations of linear systems. We prove that a system with irregular singular points is a result of isomonodromic confluence of singular points with minimal Poincaré ranks, i.e., of singular points whose Poincaré rank does not decrease under gauge transformations.
Keywords: isomonodromic deformation, linear differential equation, confluence of singular points, Poincaré rank, gauge transformation, monodromy matrix, Fuchsian system.
