By using meromorphic "characters" and "logarithms" built up from Euler's Gamma function, and by using convergent factorial series, we will give, in a first pat, a "normal form" to the solutions of a singular regular system. It will enable us to define a connexion matrix for a regular singular system. Following one of Birkhoff's idea, we will then study its link with the problem of rational ...
