The convergence of sequences of probability measures that appears at ( a ) and at ( b ) of Theorem 1.1 in this paper is signi cantly more general than the convergence in the C b(X)-weak topology of M(X) that appears in the Portmanteau theorem (for details on the C b(X)-weak topology of M(X), see
WebTo shed some light on the sense of a portmanteau theorem for unbounded measures, let us consider the question of weak convergence of inflnitely divisible probability measures „n, n 2 N towards an inflnitely divisible probability measure „0 in case of the real line R. Theorem VII.2.9 in Jacod and Shiryayev [2] gives equivalent conditions for weak convergence WebProof. For F = BL(S,d) in the Stone-Weierstrass theorem, 3 is obvious, 1 follows from Lemma 32 and 2 follows from the extension Theorem 37, since a function defined on two points …
