The aim of the summer school is to provide an introduction to several very active and related research fields in geometry and topology with a special attention to growth, asymptotic invariants of groups and spaces as well as arithmetic aspects.
Research on growth in homology rapidly developed in recent years. With regard to torsion homology growth of 3-manifolds and arithmetic locally symmetric spaces new connections between topology and number theory were found. Further, new concepts like invariant random subgroups emerged.
Dehn functions have for example played an important role in Gromov's program to classify finitely presented groups up to quasi-isometry.
