摘要

We focus on the d-boundedness of the Bergman metric on a kind of quasi-homogeneous Hartogs domain without assuming the weight function to be plurisubharmonic. As corollaries, the Kähler hyperbolicity and a vanishing theorem can be obtained. Then we generalize these results to the high-dimensional case of the fiber of the Hartogs domain. Finally, we give a more explicit explanation for the condition of the weight function which is not plurisubharmonic but makes the Hartogs domain to be quasi-homogeneous.
