The nonsingular submatrices of maximum order of the complete and the reduced incidence matrices over the real jield of a graph are shown to be in one-to-one correspondence with the odd generalized circuits and the odd generalized k-trees of the graph, respectively. It is also shown that the positiv

Let V be a vector space of dimension n β‰₯ 3 over GF(2). We are concerned with the incidence of k-dimensional subspaces in (k + 2)-dimensional subspaces where 1 ≀ k ≀ n -2. We compute here an upper bound for the rank of the associated incidence matrices over GF(2).
