Abstract
For an odd integer n=2d−1, let B(n,d) be the subgraph of the hypercube Qn induced by the two largest layers. In this paper, we describe the typical structure of independent sets in B(n,d) and give precise asymptotics on the number of them. The proofs use Sapozhenko's graph container method and a recently developed method of Jenssen and Perkins, which combines Sapozhenko's graph container lemma with the cluster expansion for polymer models from statistical physics.
