Galois theory, graphs and free groups

Research output: Working paperPreprint


A self-contained exposition is given of the topological and Galois-theoretic properties of the category of combinatorial 1-complexes, or graphs, very much in the spirit of Stallings. A number of classical, as well as some new results about free groups are derived.
