Abstract

In 1983, N. Herrndorf proved that for a ϕ\phi-mixing sequence satisfying the central limit theorem and lim infnσn2n>0\liminf_{n\to\infty}\frac{\sigma^2_n}n>0, the weak invariance principle takes place. The question whether for strictly stationary sequences with finite second moments and a weaker type (α\alpha, β\beta, ρ\rho) of mixing the central limit theorem implies the weak invariance principle remained open. We construct a strictly stationary β\beta-mixing sequence with finite moments of any order and linear variance for which the central limit theorem takes place but not the weak invariance principle.
