设M为具有强伪凸复Finsler度量F的复流形,给出了与F相关的复Rund连接、复Berwald连接和复Hashiguchi连接的刻画。得到了F的全纯截面曲率、全纯等分曲率和Ricci标量曲率在这些连接下的精确关系。进一步证明了F的保形变化F ~ = e σ (z) F是M上的弱复伯瓦尔德度规当且仅当F是M上的弱复伯瓦尔德度规。
Let M be a complex manifold endowed with a strongly pseudoconvex complex Finsler metric F. In this paper, characterizations of the complex Rund connection, complex Berwald connection and complex Hashiguchi connection that associated to F are given. The precise relationship of holomorphic sectional curvature, holomorphic bisectional curvature and Ricci scalar curvature of F with respect to these connections are obtained. Moreover, it is proved that the conformal change F˜= e σ (z) F of F is a weakly complex Berwald metric on M if and only if F is a weakly complex Berwald metric on M.
