WebTheorem 2.1. Let B be a basis matrix of the tension T(D) of a digraph D, and C the basis matrix of the °ow space F(D).Given a nonempty subset S ‰ A(D). (a) The columns of BjS are linearly independent ifi S does not contain cycle. (b) The columns of CjS are linearly independent ifi S does not contain bond. Proof. (a) Let b(a) denote the column vector of … Webow lattice of (1;T 1) is isomorphic to the q-ow lattice of (2;T 2) if and only if there is a cycle preserving bijection from the edges of 1 to the edges of 2 taking the spanning tree T 1 to …
