We give an affirmative solution to a conjecture of Cheng proposed in 1979 which asserts that the Bergman metric of a smoothly bounded strongly pseudoconvex domain in n,n2, is Kähler–Einstein if and only if the domain is biholomorphic to the ball. We establish a version of the classical Kerner theorem for Stein spaces with isolated singularities which has an immediate application to construct a hyperbolic metric over a Stein space with a spherical boundary.

Bergman–Einstein度量,具有球面边界的Kerner定理和Stein空间的推广

对于1979年提出的Cheng的猜想,我们给出肯定的解决方案,该猜想断言一个光滑有界强伪凸域的Bergman度量在 ññ2,并且仅当该域对球是全同形时,才是Kähler–Einstein。我们建立了带有孤立奇异性的Stein空间的经典Kerner定理的一个版本,该定理具有立即应用,可以在具有球形边界的Stein空间上构造双曲度量。
