Title:Stationary and convergent strategies in Choquet games
Seminar:Logic Seminar
Speaker:Carl Mummert, Marshall University, West Virginia
We study a family of games that generalize the strong Choquet game from descriptive set theory. Two types of winning strategies for the second player are of interest: stationary strategies, in which the strategy only depends on the most recent move of the first player, and convergent strategies, in which the second player tries to make the intersection of the sets played as small as possible. We prove a sufficient topological condition for the existence of a stationary winning strategy in the Choquet game, and obtain a characterization of the spaces for which the second player has a convergent winning strategy. This is joint work with Francois Dorais.
