Abstract

In this paper, we use Takeuchi's Theorem to show that for every Lipschitz pseudoconvex domain Ω\Omega in CPn\mathbb{CP}^n there exists a Lipschitz defining function ρ\rho and an exponent 0<η<10<\eta<1 such that (ρ)η-(-\rho)^\eta is strictly plurisubharmonic on Ω\Omega. This generalizes a result of Ohsawa and Sibony for C2C^2 domains. In contrast to the Ohsawa-Sibony result, we provide a counterexample demonstrating that we may not assume ρ=δ\rho=-\delta, where δ\delta is the geodesic distance function for the boundary of Ω\Omega.
