The star avoidance game

Abstract

Let n,kn, k be positive integers. The (k+1)(k+1)-star avoidance game on KnK_n is played as follows. Two players take it in turn to claim a (previously unclaimed) edge of the complete graph on nn vertices. The first player to claim all edges of a subgraph isomorphic to a (k+1)(k+1)-star loses. Equivalently, each player must keep all degrees in the subgraph formed by his edges at most kk. If all edges have been chosen and neither player has lost, the game is declared a draw. We prove that, for each fixed kk, the game is a win for the second player for all nn sufficiently large.
