Tn)L T if and only if any of the following conditions holds: (a) limn!1 Efh(Tn)g = Efh(T)g for every bounded continuous function h: Rd!

R WebbWe will need a particular statement from the portmanteau theorem: that convergence in distribution is equivalent to Fix an arbitrary closed set F ⊂ S′. Denote by g−1 ( F) the pre-image of F under the mapping g: the set of all points x ∈ S such that g ( x )∈ F. Consider a sequence { xk } such that g ( xk )∈ F and xk → x.
