The general question we consider is to characterize the memory size of winning strategies in two-player games.
In this talk, I will show that for the special case of safety conditions (aka topologically closed conditions), the minimal number of memory states of a strategy ensuring a safety condition is given by the size of the maximal antichain of left quotients with respect to language inclusion.
