On Dedekind's problem, a sparse version of Sperner's theorem, and antichains of a given size in the Boolean lattice

open access: yesJournal of the London Mathematical Society, Volume 114, Issue 1, July 2026.
Abstract Dedekind's problem, dating back to 1897, asks for the total number ψ(n)$\psi (n)$ of antichains contained in the Boolean lattice Bn$B_n$ on n$n$ elements. We study Dedekind's problem using a recently developed method based on the cluster expansion from statistical physics, and as a result, obtain several new results on the number and typical ...
