Background
Robert Bieri's original interest in homological methods for infinite groups (cohomological dimension and Poincare type duality) shifted towards geometric and
— more recently — asymptotic methods. He relates geometric properties at infinity of groups and G-spaces with algebraic properties of these groups, their group rings and their modules. The focus is on familiar groups such as metabelian, soluble, free and linear, or fundamental groups of 3-manifolds. He also met Thompson's group F and other PL-homeomorphism groups on the way and had an encounter with tropical geometry.
