Analyzing the Wu metric on a class of eggs in $\mathbb{C}^n$ -- I

Abstract: We study the Wu metric on convex egg domains of the form [ 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 $m \geq 1/2, m \neq 1$. The Wu metric is shown to be real analytic everywhere except on a lower dimensional subvariety where it fails to be $C<sup>2$-smooth. Overall however, the Wu metric is shown to be continuous when $m=1/2$ and even $C<sup>1$-smooth for each $m&gt;1/2$, and in all cases, a non-K\"ahler Hermitian metric with its holomorphic curvature strongly negative in the sense of currents. This gives a natural answer to a conjecture of S. Kobayashi and H. Wu for such $E_{2m}$.
