Résumé - Abstract

Let $X$ be a complex analytic curve. In this paper we prove that the subanalytic sheaf of tempered holomorphic solutions of $\mathcal{D}$-modules on $X$ induces a fully faithful functor on a subcategory of germs of formal holonomic $\mathcal{D}$-modules. Further, given a germ $\mathcal{M}$ of holonomic $\mathcal{D}$-module, we obtain some results linking the subanalytic sheaf of tempered solutions of $\mathcal{M}$ and the classical formal and analytic invariants of $\mathcal{M}$.
