1. Dynkin systems - Probability
Tutorial 1: Dynkin systems 3 Show that D(A) is a Dynkin system on Ω such that A⊆D(A), and that it is the smallest Dynkin system on Ω with such property, (i.e. if D is a Dynkin system on Ω with A⊆D,thenD(A) ⊆D). Definition 3 Let A⊆P(Ω).WecallDynkin system generated by A, the Dynkin system on Ω,denotedD(A), equal to the intersection of all Dynkin systems on Ω, which contain A.
