摘要

本文通过寻找直接像上Berndtsson定理的一个逆，得到了直接像的相对Bergman核的对数多次调和性、Griffiths正性和Nakano正性与自然L^2度规之间的等价关系。得到了Berndtsson对Kiselman极小原理的推广的一个逆式。

On the positivity of direct image bundles

In the present paper, we obtain an equivalent relation between the log-plurisubharmonicity of the relative Bergman kernel, the Griffiths and Nakano positivity for the direct image with the natural $L^2$ metric, by finding a converse of Berndtsson's theorem on the direct image. A converse of Berndtsson's generalization of Kiselman minimal principle is also obtained.
