Abstract

We show that each pseudoconvex domain ΩCn\Omega\subset {\mathbb C}^n admits a holomorphic map FF to Cm{\mathbb C}^m with FC1eC2δ^6|F|\le C_1 e^{C_2 \hat{\delta}^{-6}}, where δ^\hat{\delta} is the minimum of the boundary distance and (1+z2)1/2(1+|z|^2)^{-1/2}, such that every boundary point is a Casorati-Weierstrass point of FF. Based on this fact, we introduce a new anti-hyperbolic concept --- universal dominability. We also show that for each α>6\alpha>6 and each pseudoconvex domain ΩCn\Omega\subset {\mathbb C}^n, there is a holomorphic function ff on Ω{\Omega} with fCαeCαδ^α|f|\le C_\alpha e^{C_\alpha' \hat{\delta}^{-\alpha}}, such that every boundary point is a Picard point of FF. Applications to the construction of holomorphic maps of a given domain onto some Cm{\mathbb C}^m are given.
