WebPower set. In mathematics, the power set of a set S, written as or , [1] is the set of all subsets of S. In terms of cardinality, a power set is larger than the set it originates from. If … In mathematics, the power set (or powerset) of a set S is the set of all subsets of S, including the empty set and S itself. In axiomatic set theory (as developed, for example, in the ZFC axioms), the existence of the power set of any set is postulated by the axiom of power set. The powerset of S is variously denoted … See more If S is the set {x, y, z}, then all the subsets of S are • {} (also denoted $${\displaystyle \varnothing }$$ or $${\displaystyle \emptyset }$$, the empty set or the null set) • See more If S is a finite set with the cardinality S = n (i.e., the number of all elements in the set S is n), then the number of all the subsets of S is P(S) = 2 . … See more The binomial theorem is closely related to the power set. A k–elements combination from some set is another name for a k–elements subset, so the number of combinations, denoted as C(n, k) (also called binomial coefficient) is a number of subsets with k … See more In category theory and the theory of elementary topoi, the universal quantifier can be understood as the right adjoint of a functor between power sets, the inverse image functor … See more In set theory, X is the notation representing the set of all functions from Y to X.
