WebConnectivity. Connectivity is a basic concept of graph theory. It defines whether a graph is connected or disconnected. Without connectivity, it is not possible to traverse a graph from one vertex to another vertex. A graph is said to be connected graph if there is a path between every pair of vertex. From every vertex to any other vertex there ... Webjin a graph given the adjacency matrix of the graph. 3. Basic Properties of The Laplacian Matrix One of the most interesting properties of a graph is its connectedness. The Laplacian matrix provides us with a way to investigate this property.
