Telgarksy's Conjecture

Pitt Topology Seminar

Title: Telgarksy's Conjecture


A k-tactic in the Banach-Mazur game on a space X is a winning strategy for a player that only depends on the opponent's previous k moves. In 1985, Debs constructed a space X for which the NONEMPTY player has a 2-tactic, but does not have a 1-tactic. Telgarsky conjectured that for each k greater than 0, there is a space X for which NONEMPTY has a (k+1)-tactic but no k-tactic. In this talk, I will talk about joint work with Brian, Dow, and Milovich and discuss some open questions on the topic.
