A graph manifold is a 3-manifold M modelled on a nite graph as follows: 1) Each vertex v of corresponds to a Seifert bered space, denoted by Mv and called a vertex manifold; 2) Each edge e of corresponds to a 3-manifold homeomorphic to (torus) S1, denoted by Me and called an …
In topology, a graph manifold (in German: Graphenmannigfaltigkeit) is a 3-manifold which is obtained by gluing some circle bundles. They were discovered and classified by the German topologist Friedhelm Waldhausen in 1967. This definition allows a very convenient combinatorial description as a graph whose vertices are the fundamental parts and ...
