Letbe zero-mean stationary Gaussian sequence of random variables with covariance functionsatisfying. Letbe a function such thatand assume thathas Hermite rank. The celebrated Breuer–Major theorem asserts that, ifthen the finite dimensional distributions ofconverge to those of, whereWis a standard Brownian motion andis some (explicit) constant. Surprisingly, and despite the fact this theorem has become over the years a prominent tool in a bunch of different areas, a necessary and sufficient condition implying the weak convergence in the spaceof càdlàg functions endowed with the Skorohod topology is still missing. Our main goal in this paper is to fill this gap. More precisely, by using suitable boundedness properties satisfied by the generator of the Ornstein–Uhlenbeck semigroup, we show that tightness holds under the sufficient (and almost necessary) natural condition thatfor some.
