Abstract:
We construct a basis of solutions for a micro-differ\-ential equation with Fuchsian singularities in microfunctions with one holomorphic parameter. More precisely, we construct solutions written by formal symbols with one holomorphic parameter. For such an equation of order $m$, we get $(m-1)$-regular formal symbols and one singular formal symbol; the latter is not holomorphic along the Fuchsian singularities but has boundary values in the sense of microfunctions.
