Abstract

We prove the existence of functions ff in the Bloch space of the unit ball BN\mathbb{B}_N of CN\mathbb{C}^N with the property that, given any measurable function φ\varphi on the unit sphere SN\mathbb{S}_N, there exists a sequence (rn)n(r_n)_n, rn(0,1)r_n\in (0,1), converging to 11, such that for every wBNw\in \mathbb{B}_N, f(rn(ζw)+w)φ(ζ) as n, for almost every ζSN.f(r_n(\zeta -w)+w) \to \varphi(\zeta)\text{ as }n\to \infty\text{, for almost every }\zeta \in \mathbb{S}_N. The set of such functions is residual in the little Bloch space. A similar result is obtained for the Bloch space of the polydisc.
