Abstract

We study the Wu metric for the non-convex domains of the form E2m={zCn:z12m+z22++zn12+zn2<1}, E_{2m} = \big\{ z \in \mathbb{C}^n : \vert z_1 \vert^{2m} + \vert z_2 \vert^2 + \ldots + \vert z_{n-1} \vert^2 + \vert z_n \vert^{2} <1 \big \}, where 0<m<1/2 0 < m < 1/2. Explicit expressions for the Kobayashi metric and the Wu metric on such pseudo-eggs E2mE_{2m} are obtained. The Wu metric is then verified to be a continuous Hermitian metric on E2m E_{2m} which is real analytic everywhere except along the complex hypersurface Z={(0,z2,,zn)E2m} Z = \{ (0, z_2, \ldots, z_n ) \in E_{2m} \} . We also show that the holomorphic sectional curvature of the Wu metric for this non-compact family of pseudoconvex domains is bounded above in the sense of currents by a negative constant independent of mm. This verifies a conjecture of S. Kobayashi and H. Wu for such E2mE_{2m}.
