Hence it is a connected graph. G1 has 7(7-1)/2 = 21 edges . Trees Definition 1.1.A graph G is connected, if for any vertices u and v, G contains a path from u to v.Otherwise, we say G is disconnected. But we can make graph disconnected by removing more than 1 vertex, for example if we remove 4,6 vertices graph becomes disconnected. A null graph of more than one vertex is disconnected (Fig 3.12). Also, we should note that a spanning tree covers all the vertices of a given graph so it can’t be disconnected. representation deleted , so the number of edges decreases . ⇒ 1. ) Then, Volume V.

In graph theory, a tree is an undirected graph in which any two vertices are connected by exactly one path, or equivalently a connected acyclic undirected graph. and Removing any edge makes G disconnected, because a graph with n vertices clearly needs at least n −1 edges to be connected. number of bills But we can make graph disconnected by removing more than 1 vertex, for example if we remove 4,6 vertices graph becomes disconnected. Therefore, G is isomorphic to G. 6. Ask Question Asked 9 years, 7 months ago. In above graph there are no articulation points because graph does not become disconnected by removing any single vertex. 2. Disconnected Graph: A graph is called disconnected if there is no path between any two of its vertices. In graph theory, the degree of a vertex is the number of connections it has. Example- Here, This graph consists of two independent components which are disconnected. = COs GraphPlot[Table[1, {6}, {6}], EdgeRenderingFunction -> None] Explanation: After removing either B or C, the graph becomes disconnected. 17622 Advanced Graph Theory IIT Kharagpur, Spring Semester, 2002Œ2003 Exercise set 1 (Fundamental concepts) 1.
