- powerdomain — (theory) The powerdomain of a domain D is a domain containing some of the subsets of D. Due to the asymmetry condition in the definition of a partial order (and therefore of a domain) the powerdomain cannot contain all the subsets of D. This is because there may be different sets X and Y such that X <= Y and Y <= X which, by the asymmetry condition would have to be considered equal. There are at least three possible orderings of the subsets of a powerdomain: Egli-Milner: X <= Y iff for all x in X, exists y in Y: x <= y and for all y in Y, exists x in X: x <= y ("The other domain always contains a related element"). Hoare or Partial Correctness or Safety: X <= Y iff for all x in X, exists y in Y: x <= y ("The bigger domain always contains a bigger element"). Smyth or Total Correctness or Liveness: X <= Y iff for all y in Y, exists x in X: x <= y ("The smaller domain always contains a smaller element"). If a powerdomain represents the result of an abstract interpretation in which a bigger value is a safe approximation to a smaller value then the Hoare powerdomain is appropriate because the safe approximation Y to the powerdomain X contains a safe approximation to each point in X.
