Abstract

We characterize the (κ,λ, <μ)-distributive law in Boolean algebras in terms of cut and choose games 𝔖κ(λ), when μ≤κ≤λ and κ=κ. This builds on previous work to yield game-theoretic characterizations of distributive laws for almost all triples of cardinals κ,λ,μ with μ≤λ, under GCH. In the case when μ≤κ≤λ and κ=κ, we show that it is necessary to consider whether the κ-stationarity of 𝒫κ+λ in the ground model is preserved by 𝔹. In this vein, we develop the theory of κ-club and κ-stationary subsets of 𝒫κ+λ. We also construct Boolean algebras in which Player I wins 𝔖κκ+) but the (κ,∞,κ)-d.l. holds, and, assuming GCH, construct Boolean algebras in which many games are undetermined.
