Nowhere-Zero Flows in Random Graphs
✍ Benny Sudakov 📂 Article 📅 2001 🏛 Elsevier Science 🌐 English ⚖ 138 KB

A nowhere-zero 3-flow in a graph G is an assignment of a direction and a value of 1 or 2 to each edge of G such that, for each vertex v in G, the sum of the values of the edges with tail v equals the sum of the values of the edges with head v. Motivated by results about the region coloring of planar

## Abstract In this paper, we characterize graphs whose tensor product admit nowhere‐zero 3‐flow. The main result is: For two graphs __G__~1~ and __G__~2~ with δ ≥ 2 and __G__~2~ not belonging to a well‐characterized class of graphs, the tensor product of __G__~1~ and __G__~2~ admits a nowhere‐zero

## Abstract Let __G__ be a graph. For each vertex __v__ ∈__V__(__G__), __N~v~__ 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__), __N~v~__ is __k__‐edge‐connected. In this paper we study t

## Abstract A graph __G__ is an odd‐circuit tree if every block of __G__ is an odd length circuit. It is proved in this paper that the product of every pair of graphs __G__ and __H__ admits a nowhere‐zero 3‐flow unless __G__ is an odd‐circuit tree and __H__ has a bridge. This theorem is a partial r

Let G be a 2-edge-connected simple graph with order n. We show that if IV(G)l 5 17, then either G has a nowhere-zero 4-flow, or G is contractible to the Petersen graph. We also show that for n large, if I€(G)J L (' 2 17) + 34, then either G has a nonwhere-zero 4-flow, or G can be contracted to the P
