Incidence. In a graph , two edges are incident if they share a common vertex. For example, edge and edge are incident as they share the same vertex . Also, we can define the incidence over a vertex. A vertex is an incident to an edge if the vertex is one of the two vertices the edge connects. See more Suppose we have a graph with vertices, we can use a square matrix to represent the adjacency relationships among these vertices. For … See more We can also use an adjacency list to represent a graph. For example, the adjacency list of the example graph is: In this table, each row contains a list of vertices that is adjacent to the current vertex . Each pair … See more For a dense graph, where the number of edges is in the order of , the adjacency matrix and adjacency list have the same time and space complexity. However, if the graph is sparse, … See more WebIf it is FALSE then a single edge is created for every non-zero element in the incidence matrix.

WebThe incidence matrix of an undirected graph has no negative entries. The sum of the elements in any column of incidence matrix of an undirected graph is always 2. The incidence matrix of a directed graph has some negative entries. If a directed graph has no self-loops, the sum of the elements of its incidence matrix is always 0.
