摘要:
It is conjectured by Vizing (1965) that every planar graphs graph G with maximum degree 6 <= Delta <= 7 is class one. The case Delta = 7 was confirmed independently by Sanders and Zhao (2001), and by Zhang (2000). In this paper, we prove that every planar graph G with Delta = 6 and without 7-cycles is class one.
