WebLemma 3 For all bipartite graphs G, the incidence matrix A is totally unimodular. Proof: Recall that A is a 0-1 matrix, where columns are indexed by edges and each column has exactly two 1’s, corresponding to the two vertices of the edge. We proceed by induction. The claim is certainly true for a 1 1 matrix. WebIt is the incidence matrix of any bidirected graph that orients the given signed graph.
