Karen VOGTMANN - Spaces of Graphs, Tori and Other Flat Gamma-complexes
Spaces of finite graphs play a key role in perturbative quantum field theory, but also in many other areas of science and mathematics. Among these is geometric group theory, where they are used to model groups of automorphism of free groups. Graphs can be thought of as 1-dimensional flat m
