Unbounded visibility domains: metric estimates and an application

Complex Variables 2025-07-02 v3 Metric Geometry

Abstract

We give an explicit lower bound, in terms of the distance from the boundary, for the Kobayashi metric of a certain class of bounded pseudoconvex domains in Cn\mathbb{C}^n with C2\mathcal{C}^2-smooth boundary using the regularity theory for the complex Monge--Ampere equation. Using such an estimate, among other tools, we construct a family of unbounded Kobayashi hyperbolic domains in Cn\mathbb{C}^n having a certain negative-curvature-type property with respect to the Kobayashi distance. As an application, we prove a Picard-type extension theorem for the latter domains.
