  • Abstract: Groups of (S-)arithmetic origin are of great interest to algebraists, geometers, and number theorists alike. Unsurprisingly, their topological properties are important to all such areas. This talk will be an overview on some cohomological properties of (S-)arithmetic groups, focusing on concrete examples, famous results, and decisive 'parameters' in the theory. Towards the end we shall also discuss more recent results, shifting focus to arithmetic subgroups of classical semisimple groups based on joint work with B. Brück and R. Sroka.
