WebNov 1, 2011 · Abstract. The circular flow number Φ c ( G, σ) of a signed graph ( G, σ) is the minimum r for which an orientation of ( G, σ) admits a circular r -flow. We prove that the circular flow number of a signed graph ( G, σ) is equal to the minimum imbalance ratio of an orientation of ( G, σ). WebIn graph theory, a nowhere-zero flow or NZ flow is a network flow that is nowhere zero. It is intimately connected (by duality) to coloring planar graphs . Definitions [ edit] Let G = ( V, E) be a digraph and let M be an abelian group. A map φ: E → M is an M-circulation if for every vertex v ∈ V
