WebRemark: In the statement of Donsker’s theorem I have ignored measurability diﬃculties related to the fact that D(R,k·k ∞) is a nonseparable Banach space. For the most part (the exception is in Sections 1.2 and 1.3), I will continue to ignore these diﬃculties throughout these lecture notes. For a complete treatment of the Webin probability, and, by Donsker’s theorem and Slutsky’s theorem, we conclude the convergenceof ﬁnite-dimensionaldistributions.
