Abstract

In 1968, Vizing [Uaspekhi Mat Nauk 23 (1968) 117-134; Russian Math Surveys 23 (1968), 125-142] conjectured that for any edge chromatic critical graph G = (V, E) with maximum degree Delta, vertical bar E vertical bar >= 1/2 {(Delta-1)vertical bar V vertical bar + 3}. This conjecture has been verified for Delta <= 5. In this article, by applying the discharging method, we prove the conjecture for Delta = 6. (C) 2008 Wiley Periodicals, Inc.
