Abstract

The paper studies complex manifolds whose Bergman metrics are incomplete but have constant holomorphic sectional curvature. We will construct a real analytic unbounded domain in C2 whose Bergman metric is well-defined and has a positive constant holomorphic sectional curvature, which appears to be the first example of this kind. We will answer a long standing folklore conjecture that a Stein manifold has a negative constant holomorphic sectional curvature if and only if it is biholomorphic to a ball with a pluripolar set removed. Together with the uniqueness of a moment problem in the appendix of the paper provided by John Treuer, we will show that, under natural assumptions, there is no complex manifold whose Bergman metric is flat.
