Abstract

In this paper, we explore some connections between Kobayashi geometry and the Dirichlet problem for the complex Monge--Amp\`ere equation. Among the results we obtain through these connections are: (i)(i)~a theorem on the continuous extension up to D\partial{D} of a proper holomorphic map F:DΩF: D\longrightarrow \Omega between domains with dimC(D)<dimC(Ω)\dim_{\mathbb{C}}(D) < \dim_{\mathbb{C}}(\Omega), and (ii)(ii)~a result that establishes the existence of bounded domains with ``nice'' boundary geometry on which H\"older regularity of the solutions to the complex Monge--Amp\`ere equation fails. The first, a result in Kobayashi geometry, relies upon an auxiliary construction that involves solving the complex Monge--Amp\`ere equation with H\"older estimates. The second result relies crucially on a bound for the Kobayashi metric.
