Drawing strategies in Strong Ramsey games for 3-uniform hypergraphs

Abstract

The Strong Ramsey game R(B,G)\mathcal{R}(B,G) is a two player game with players P1P_1 and P2P_2, where BB and GG are kk-uniform hypergraphs for some k2k \geq 2. GG is always finite, while BB may be infinite. P1P_1 and P2P_2 alternately color uncolored edges eBe \in B in their respective color and P1P_1 begins. Whoever completes a monochromatic copy of GG in their own color first, wins the game. If no one claims a monochromatic copy of GG in a finite number of moves, the game is declared a draw. In this paper, we give an infinite set of 3-uniform hypergraphs {Gt}t3\{G_t\}_{t \geq 3}, such that P2P_2 has a drawing strategy in the Strong Ramsey game R(K0(3),Gt)\mathcal{R}(K_{\aleph_0}^{(3)}, G_t). This improves a result by David, Hartarsky and Tiba.
