Pi system
In mathematics, a π-system on a set Ω is a collection P of certain subsets of Ω, such that P is non-empty. A ∩ B ∈ P whenever A and B are in P. That is, P is a non-empty family of subsets of Ω that is closed under finite intersections. The importance of π-systems arise from the fact that if two probability measures agree on a π-system, then they agree on the σ-algebra generated by that π-system. Moreover, if other properties, such as equality of integrals, hold for the π-system, then they hold for the generated σ-algebra as well. This is the case whenever the collection of subsets for which the property holds is a λ-system. π-systems are also useful for checking independence of random variables. This is desirable because in practice, π-systems are often simpler to work with than σ-algebras. For example, it may be awkward to work with σ-algebras generated by infinitely many sets . So instead we may examine the union of all σ-algebras generated by finitely many random sets . This forms a π-system that generates the desired σ-algebra.
