The game chromatic number refers to the smallest integer k such that the first player Alice is assumed of a victory in the coloring game variety wherein Alice and Bob take turns in coloring vertices of a graph, with the only rule that adjacent vertices cannot have the same color. Alice wins if all vertices have been colored. Otherwise, Bob wins. This thesis provides the proofs for the game chromatic number of special classes of graphs which includes paths, cycles, complete graphs, complete bipartite graphs and complete bipartite-1-factor graphs, communicated by Professor Kiyoshi Ando of the University of Electrocommunications, Tokyo, Japan. The game chromatic number of the Cartesian product of graphs, specifically the product of a complete ...
