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 ... WebCertain manifold triangulations admit a particular kind of encoding as a coloured graph, in a way that allows us to uniquely recover the triangulation from the graph. This graph is called a graph-encoded manifold (gem). Gems have additional combinatorial structure that general triangulations lack. inception model architecture https://akumacreative.com
