On the generalized Riemann-Hilbert problem with irregular singularities (2004)
Bolibruch, A. A., Malek, S., Mitschi, C.
We give sufficient conditions, on data including the monodromy representation, the Stokes matrices and the Poincare ranks at prescribed singularities, to solve the generalized Riemann-Hilbert problem...

Connected Linear Groups as Differential Galois Groups (1995)
this paper we give a proof of the following
In this paper we give a proof of the following THEOREM 1.1. Let C be an algebraically closed field of characteristic zero, G a connected linear algebraic group defined o�er C, and k a differential...
On Ramis's solution of the local inverse problem of differential Galois theory (1994)
: Recently, J.P. Ramis gave necessary and sufficient conditions for a linear algebraic group to be the Galois group of a Picard-Vessiot extension of the field Cfxg[x \Gamma1 ] of germs of meromorphic...
