Abstract：Vizing’s planar graph conjecture says that every class two planar has maximum degree at most 5. The conjecture is still open. We consider the problem for graphs embeddable on a surface Sigma and attempt to find the best possible upper bound for the maximum degree of class two graphs embeddable on Sigma. In this talk I will give a survey on this topic and present some new results.
