摘要 | Let (X(n))(n >= 1) be a sequence of i.i.d.r.v.'s with values in a Polish space (E, d) of law mu. Consider the empirical measures L(n) = 1/n Sigma(n)(k=1) delta(Xk), n >= 1. Our purpose is to generalize Sanov's theorem about the large deviation principle of L(n) from the weak convergence topology to the stronger Wasserstein metric W(p). We show that L(n) satisfies the large deviation principle in the Wasserstein metric W(p) (p is an element of [1, +infinity)) if and only if integral(E) e(lambda dp(x0, x))d mu(x) < +infinity for all lambda > 0, and for some x(0) is an element of E.
