Focuses on automorphism groups of trees, providing an analysis of when two trees have isomorphic automorphism groups. This work focuses on the class of $aleph_0$-categorical trees, and for this class the analysis is complete. It discusses various open problems, mostly in permutation group theory and in model theory.
