A generalization of the Ahlswede-Daykin inequality Original Research Article

We prove an inequality concerning two n-tuples of nonnegative functions on a distributive lattice, of which the Ahlswede-Daykin inequality is the case n = 2. This is a rediscovery: Rinott and Saks proved the same inequality a little earlier. But our approach and proofs are somewhat different.Ron Aharoni, Uri Keich
