Rank and nullity of a graph

Webb(iii) Nullity of a matrix A is also the number of elements in a maximal linearly independent subset of the column vectors of A. 3.4.11 Theorem ( Rank Nullity ): Let A be a m n matrix with rank ( A) = r. Then nullity ( A) = r. Hence rank ( A) + nullity ( A) = n. A set of n -elements of which are linearly independent is called basis of Proof Webbnections with rank and nullity. These set systems have interesting descriptions in terms of matchings, vertex covers, and edges’ influence on rank – especially for trees. For a wide variety of graphs, the lattice of SZF-closed sets is also a matroid, a fact which can be used to obtain a polynomial-time algorithm for computing the skew zero ...

(RBT Levels: L1, L2 and L3) Equivalently, the rank of a graph is the rank of the oriented incidence matrix associated with the graph. [2] Analogously, the nullity of the graph is the nullity of its oriented incidence matrix, given by the formula m − n + c , where n and c are as above and m is the number of edges in the graph.
