We show for dimensions 4 and higher that almost surely the only limit points for a sequence of increasing cubes are the plus and the minus state. For d=2 and d=3 we prove a similar result for sparse sequences of increasing cubes. This question was raised by Newman and Stein. Our results imply that the Newman-Stein metastate is concentrated on the plus and the minus state.LaTeX2e, 30 pages, no figuresMathematical PhysicsProbability82B20, 82B44 (Primary) 60F05, 60K35 (Secondary)Chaotic size dependence in the Ising model with random boundary conditionstext
