A note on unfolding manifolds of meromorphic connections on the Riemann sphere with unramified singularities
Kazuki Hiroe
This note explains a construction of a Poisson manifold whose symplectic foliation describes a deformation of a moduli space of meromorphic connections with unramified irregular si…

Index of rigidity of differential equations and Euler characteristic of their spectral curves
Kazuki Hiroe
We show a coincidence of index of rigidity of differential equations with irregular singularities on a compact Riemann surface and Euler characteristic of the associated spectral c…

Generalized Whittaker functions for degenerate principal series of
Kazuki Hiroe
We give a characterization of a generalized Whittaker model of a degenerate principal series representation of as the kernel of some differential operators. By this char…
