Correlation in partially ordered sets
Basic results concerning correlation within ordered sets that focus on distributive lattices, systems of subsets ordered by proper inclusion and the family of linear extensions of an arbitrary finite ordered set are reviewed in this paper. Let us quote some interesting results: the Ahlswede-Daykin theorem, the FKG theorem, the universal correlation theorems of Winkler and Brightwell. Some theorems are proved carefully and the author mentions some open problems.
