WebTheorem 1. Suppose n is perfect for all n>0, Gis countably generated, and d: S S!R is measurable with respect to G G. Then, ( n: n 0) admits a Skorohod representation if and only if condition (2) holds. Under the assumptions of Theorem 1, Gis the Borel ˙- eld for some separable distance d on S.

In the words of mathematician and probability … WebIn particular, in assumptions of the above theorem, if X n −→ D X 0 and {X n} is uniformly tight, then one obtains the a.s. Skorokhod representation for subsequences: in every subsequence {n k} one can find a further subsequence {n k l} such that {X n kl} and X 0 admit the usual a.s. Skorokhod representation on [0,1].
WebHowever how can we apply the Skorohod representation theorem? We know there exists another probability space ( Ω ′, A, P), a sequence of r.v. X n: Ω ′ → Ω converging to X for all ω ′ ∈ Ω. The law of X is given by Q and the law of X n is given by Q n. Therefore we have E Q [ g ( S N)] = E P [ g ( S N ( X))] E Q n [ g ( S N)] = E P [ g ( S N ( X n))]
