Web28 de mai. de 2008 · A graph is said to be cyclically k-edge-connected, if at least k edges must be removed to disconnect it into two components, each containing a cycle. Such a set of k edges is called a cyclic-k-edge cutset and it is called a trivial cyclic-k-edge cutset if at least one of the resulting two components induces a single k-cycle..

WebA graph is called hypohamiltonian if it is not hamiltonian but becomes hamiltonian if any vertex is removed. Such graphs exist on orders 10 (the Petersen graph), 13, 15, 16, and all orders from 18 onwards [1]. It is elementary to show that hypohamiltonian graphs must be 3-connected and have cyclic connectivity at least 4. Web1 de jul. de 2009 · Recently, Hubenko [A.
