Özet : We concoct a uniform treatment of mapping class group​oid​s and Thompson’s groups thereby introducing their hybrid group​oid​s. As a by-product we obtain a description of the outer automorphism group of free groups as the isotropy group of a groupoid, which extends the mapping class groupoid of Mosher and Penner. We illustrate some arithmetic aspects of these groupoids at the end of our talk.
