Bounded Plurisubharmonic Exhaustion Functions for Lipschitz Pseudoconvex Domains in mathbb{CP}^n

In this paper, we use Takeuchi's Theorem to show that for every Lipschitz pseudoconvex domain $\Omega$ in $\mathbb{CP}^n$ there exists a Lipschitz defining function $\rho$ and an exponent $0<\eta<1$ such that $-(-\rho)^\eta$ is strictly plurisubharmonic on $\Omega$. This generalizes a result of Ohsawa and Sibony for $C^2$ domains. In contrast to the Ohsawa-Sibony result, we provide a counterexample demonstrating that we may not assume $\rho=-\delta$, where $\delta$ is the geodesic distance function for the boundary of $\Omega$.
