Abstract

Given a domain of holomorphy DD in CN\mathbb{C}^N, N2N\geq 2, we show that the set of holomorphic functions in DD whose cluster sets along any finite length paths to the boundary of DD is maximal, is residual, densely lineable and spaceable in the space O(D)\mathcal{O}(D) of holomorphic functions in DD. Besides, if DD is a strictly pseudoconvex domain in CN\mathbb{C}^N, and if a suitable family of smooth curves γ(x,r)\gamma(x,r), xbDx\in bD, r[0,1)r\in [0,1), ending at a point of bDbD is given, then we exhibit a spaceable, densely lineable and residual subset of O(D)\mathcal{O}(D), every element ff of which satisfies the following property: For any measurable function hh on bDbD, there exists a sequence (rn)n[0,1)(r_n)_n \in [0,1) tending to 11, such that fγ(x,rn)h(x),n, f\circ \gamma(x,r_n) \rightarrow h (x),\,n\rightarrow \infty, for almost every xx in bDbD.
