WebApply the monotone class theorem to prove Dynkin's π−λ theorem: If L is the smallest λ-system containing the π-system P, then L=σ (P). Hint: Show that L itself is a π-system, and thus it is also an algebra and a monotone class. To show L is a π-system, you need the following relation (prove it): for any set C∈L, P⊂LC:= {A∈LC:A∩C∈L}=L Webmonotone class M(A) that contains A. Simply take the intersection of all monotone classes that contain A. With this in mind, it is clear that M(A) ˙(A), the smallest ˙-algebra that contains A.
