Steinberg, Richard (1984) Tutte's 5-flow conjecture for the projective plane. Journal of graph theory, 8 (2). pp. 277-285. ISSN 0364-9024
Heawood proved that every planar graph with no 1-cycles is vertex 5-colorable, which is equivalent to the statement that every planar graph with no 1-bonds has a nowhere-zero 5-flow. Tutte has conjectured that every graph with no 1-bonds has a nowhere-zero 5-flow. We show that Tutte's 5-Flow Conjecture is true for all graphs embeddable in the real projective plane.
