Sasakian度量空间中测地线方程的正则性

Regularity of the geodesic equation in the space of Sasakian metrics

PengFei Guan, Xi Zhang

摘要:

本文研究了Sasakian度量空间中测地线方程的正则性。首先将Sasakian度量空间中的测地线方程化为Kähler锥上退化复Monge-Ampére型方程的狄利克雷问题,然后得到了上述方程的先验解.这些先验估计保证了Sasakian度量空间中任意两点的$C^{2}_{w}$测地线的存在性和唯一性。最后给出了上述估计的一些几何应用.

英文摘要:

This paper is devoted to the regularity analysis of a geodesic equation in the space of Sasakian metrics. Firstly, we reduce the geodesic equation in the space of Sasakian metrics to a Dirichlet problem of degenerate complex Monge-Ampére type eqution on the Kähler cone; secondly, we obtain a priori etimates for the above equation. These a priori estimates guarantee the existence and uniqueness of $C^{2}_{w}$ geodesic for any two points in the space of Sasakian metrics. We also give some geometric applications of the above estimates in the end of this paper.
