The game chromatic number of a random hypergraph

Combinatorics 2019-02-11 v1

Abstract

We consider the following game, played on a kk-uniform hypergraph HH. There are qq colors available and two players take it in turns to color vertices. A partial coloring is proper if no edge is mono-chromatic. One player, A, wishes to color all the vertices and the other player, B, wishes to prevent this. The {\em game chromatic number} χg(H)\chi_g(H) is the minimum number of colors for which A has a winning strategy. We consider this in the context of a random kk-uniform hypergraph and prove upper and lower bounds that hold w.h.p.
