SUMMARY:Seog-Jin Kim (김석진)\, Online DP-coloring of graphs
DESCRIPTION:Online list coloring and DP-coloring are generalizations of list coloring that attracted considerable attention recently. Each of the paint number\, $\chi_P(G)$\, (the minimum number of colors needed for an online coloring of $G$) and the DP-chromatic number\, $\chi_{DP}(G)$\, (the minimum number of colors needed for a DP-coloring of $G$) is at least the list chromatic number\, $\chi_\ell(G)$\, of $G$ and can be much larger. On the other hand\, each of them has a number of useful properties.\nWe introduce a common generalization\, online DP-coloring\, of online list coloring and DP-coloring and to study its properties. This is joint work with Alexandr Kostochka\, Xuer Li\, and Xuding Zhu.
