In this paper we consider the reconstruction problem on the tree for the hardcore model. We determine new bounds for the nonreconstruction regime on the k-regular tree showing nonreconstruction when λ (e+o(1)) ln2 k. We discuss the relationship for finding large independent sets in sparse random graphs and to the mixing time of Markov chains for sampling independent sets on trees.
