Cartan-Egg域与复欧氏空间的不相关性

多复变中某些特定度量下的域与复欧氏空间的相关性一直是近年来研究的热点问题.如果两个K?hler流形具有公共的K?hler子流形,则称它们是相关的,否则称为不相关的. Cartan-Egg域是一类非常好的有界非齐性域,其Bergman核函数的显表达式可以通过膨胀原理构造得到,研究具有Bergman度量的Cartan-Egg域与具有平坦度量的复欧氏空间的相关性是有意义的.如果一个域的Bergman核函数是Nash函数,容易分析在其诱导的Bergman度量下与复欧氏空间的相关性,而Cartan-Egg域的Bergman核函数不是Nash函数.通过分析Cartan-Egg域的Bergman核函数的偏导函数的代数性质,得到具有Bergman度量的Cartan-Egg域与具有平坦度量的复欧氏空间是不相关的.

Einstein-K(a)hler metric on Cartan-Hartogs domain of the second type

The Einstein-Kahler metric for the Cartan-Hartogs domain of the second type is described. Firstly, the Monge-Ampère equation for the metric to an ordinary differential equation in the auxiliary function X=X(z,w) is reduced, by which an implicit function in X is obtained. Secondly, for some cases, the explicit forms of the complete Einstein-Kahler metrics on Cartan-Hartogs domains which are the non-homogeneous domains are obtained. Thirdly, the estimate of holomorphic sectional curvature under the Einstein-Kahler metric is given, and in some cases the comparison theorem for Kobayashi metric and Einstein-Kahler metric on Cartan-Hartogs domain of the second type is established.     

The comparison theorem for Bergman and Kobayashi metrics on Cartan-Hartogs domain of the second type

In this paper, the holomorphic sectional curvature under invariant metric on a Cartan-Hartogs domain of the second type YII(N,p,K) is presented and an invariant K?]lher metric which is complete and not less than the Bergman metric is constructed, such that its holomorphic sectional curvature is bounded above by a negative constant. Hence a comparison theorem for the Bergman and Kobayashi metrics on YII(N,p,K) is obtained.     

The Bergman kernels on Cartan-Hartogs domain

The main point is the calculation of the Bergman kernel for the so-called Cartan-Hartogs domains. The Bergman kernels on four types of Cartan-Hartogs domains are given in explicit formulas. First by introducing the idea of semi-Reinhardt domain is given, of which the Cartan-Hartogs domains are a special case. Following the ideas developed in the classic monograph of Hua, the Bergman kernel for these domains is calculated. Along this way, the method of “inflation”, is made use of due to Boas, Fu and Straube.
