| 摘 要： | 首先证明了当‖β‖α＜1时,复Randers度量的Cartan挠率具有上界.然后推导出所构造的含有3个参数的复Randers度量要么是非弱K(a)hler Finsler度量,要么满足(β)b0|0+βb-0|0≠0,并且该度量具有一致上界.最后给出一些例子说明如果ρ2+λε=0,那么它们的全纯曲率都是非正的.

| Abstract: | First,this paper shows that when || β|| α<1 the Cartan torsion of the complex Randers metric has a upper bound.Next,we derive that this constructed 3-parameter family of the complex Randers metrics is either a non-weakly Khler Finsler metric or β b0|0+β b0|0≠0.Meanwhile,it has the uniform upper bounded for Cartan torsion.At last some examples are given to indicate that their holomorphic curvatures are non-positive if ρ2+λε=0. |
