A Short Proof of Seymour’s 6-Flow Theorem

Key Points

• Demonstrates every 2-edge-connected graph supports a nowhere-zero flow in Z2 x Z3, simplifying existing proofs.
• The approach utilizes a compact variation of an earlier proof, making it more accessible yet effective.
• Integrates key concepts in graph theory to establish this theorem, relevant in wider applications.
• Emphasizes a crucial characteristic of 2-edge connectivity, which significantly impacts flow properties in graphs.
