Let G be a graph. For each vertex v ∈V(G), Nv denotes the subgraph induces by the vertices adjacent to v in G. The graph G is locally k-edge-connected if for each vertex v ∈V(G), Nv is k-edge-connected. In this paper we study the existence of nowhere-zero 3-flows in locally k-edge-connected graphs. In particular, we show that every 2-edge-connected, locally 3-edge-connected graph admits a nowhere-zero 3-flow. This result is best possible in the sense that there exists an infinite family of 2-edge-connected, locally 2-edge-connected graphs each of which does not have a 3-NZF. © 2003 Wiley Periodicals, Inc.
