The goal of this thesis is to obtain results of classification of complex compact manifolds equipped with some rigid meromorphic geometric structures (in the sens of M. Gromov). To this end, we use a result proved by S. Dumitrescu, stating that a such geometric structure is quasihomogeneous in the case that the base manifold has only constant meromorphic functions. The quasi-homogeneity ensures the existence of a family of germs of infinitesimal symetries for the structure, whose evaluations at a point of the base manifold span its tangent space.In the holomorphic case, on a simply connected base manifold, the germs of infinitesimal symetries as above are the restrictions of global infinitesimal symetries of the structure. These infinitesi...
