Isomonodromic degenerations of irregular singularities

Claude Sabbah

École Polytechnique



Abstract: Part of the work of Andrey Bolibrukh has been concerned with isomonodromic confluence of regular singularities of differential equations. In this talk, I will consider cases with irregular singularities, inspired by the work of Cotti, Dubrovin and Guzzetti. I will emphasize the use of asymptotic normal forms for irregular singularities in higher dimensions.
