Outline of Final Research Achievements

We partially quantized the simply-laced isomonodromy systems.
By joint work with Philip Boalch, we constructed the wild character varieties as algebraic Poisson varieties. Furthermore, we introduced the notions of filtered meromorphic connections on Riemann surfaces and filtered Stokes local systems, and established an equivalence between their categories.
We explicitly described the fundamental two-forms of the isomonodromic deformation equations for unramified meromorphic connections on the Riemann sphere. Furthermore, we use this result and some previous results to obtain a new description of the isomonodromic deformation equations as non-autonomous Hamiltonian systems.
