摘要
Let beta be a standard Brownian motion, let X be an alpha-stable process, and let f = (mu) over cap be the Fourier transform of a discrete measure. It is shown that weakly in C([0,+infinity)), eta(alpha/2) integral(t)(0) f (eta X(s))ds double right arrow root C(f,alpha)beta(t) as eta+infinity, or equivalently 1/root lambda integral(lambda t)(0) f(X(s))ds double right arrow root C(f,alpha)beta(t) as lambda+infinity.
