报告人简介:罗荣,美国西弗吉尼亚大学(West Virginia UniversityUSA)数学系教授。主要研究图的染色理论和流的理论,是国际知名的染色问题专家。发表50余篇论文,多数是发表在图论顶尖杂志上,如Journal of Cominatorial Theory Ser. B,  Journal of Graph Theory,  SIAM Journal on Discrete Math,  European J. of Combinatorics.

报告摘要 Vizing’s planar graph conjecture says that every class two planar has maximum degree at most 5.  The conjecture is still open.  In this talk, I will discuss edge coloring of graphs on general surfaces. Some new recent results will be introduced.
