Abstract
In a complex domain , let be a linear holomorphic partial differential operator and be its characteristic hypersurface. When the localization of at is a Fuchsian operator having a non-negative integral characteristic index, it is proved, under some conditions, that every holomorphic solution to in has a holomorphic extension in . Besides, it is applied to the propagation of singularities for equations with non-involutive double characteristics.
