Topological Symmetry Groups of Graphs in 3-Manifolds
Abstract
We prove that for every closed, connected, orientable, irreducible 3-manifold, there exists an alternating group A_n which is not the topological symmetry group of any graph embedded in the manifold. We also show that for every finite group G, there is an embedding {\Gamma} of some graph in a hyperbolic rational homology 3-sphere such that the topological symmetry group of {\Gamma} is isomorphic to G.
