Direct products of free groups in Aut(F_N)
We give a complete description of the embeddings of direct products of nonabelian free groups into Aut(F<sub>N</sub>) and Out(F<sub>N</sub>) when the number of direct factors is maximal. To achieve this, we prove that the image of each such embedding has a canonical fixed poi...

| Summary: | We give a complete description of the embeddings of direct products of nonabelian free groups into Aut(F<sub>N</sub>) and Out(F<sub>N</sub>) when the number of direct factors is maximal. To achieve this, we prove that the image of each such embedding has a canonical fixed point of a particular type in the boundary of Outer space. |
