Weak convergence for multiple stochastic integrals in Skorohod space

Yoon Tae Kim


By  using the multidimensional normal approximation of functionals of Gaussian fields, we prove that functionals of Gaussian fields, as functions of $t$, converge weakly  to a standard Brownian motion. As an application, we consider  the convergence of  the Stratonovich-type Riemann sums, as a function of $t$, of fractional Brownian motion with Hurst parameter $H=1/4$.
