AbstractFor six natural notions of cloud-antichains in a partially ordered set P we determine asymptotically their maximal lengths if P is the family of all subsets of a finite set. Actually, in three cases we even have exact results
We present new exact and asymptotic results about the size of the largest antichain in the product o...
