A note on integrability and finite orbits for subgroups of Diff (C, 0).

In this note we extend to arbitrary dimensions a couple of results due respectively to Mattei-Moussu and to Camara-Scardua in dimension 2. We also provide examples of singular foliations having a Siegel-type singularity and answering a question independently raised by Abate and by Genzmer. [ABSTRACT FROM AUTHOR]
