Title: A tale of two groups - mapping class group and outer automorphism group of free group Abstract: In this talk I will define two key groups studied in geometric group theory - the mapping class group of a surface and the outer automorphism group of a free group. I will discuss how the theory of mapping class groups has motivated and guided the study of Out(F_n). Both groups act on certain hyperbolic simplicial complexes. For mapping class group these actions yield useful information about the group such as homological stability, finite asymptotic dimension, quasi-isometric rigidity. I will define some of these hyperbolic complexes and classifythe group elements that act with positive translation length.
