报告题目：Some history and applications of generalized coloring numbers
摘要：I will survey applications of generalized coloring numbers to problems in Ramsey theory, graph coloring, game chromatic number, packing, and dimension of ordered sets. In particular I will use them to prove upper bounds on the chromatic number of exact distance graphs of planar graphs.
