Sasakian空间形式中平截面的截面曲率

The Sectional Curvature of a Plane Section in a Sasakian Space Form

给出了Sasakian空间形式的截面曲率与φ一截面曲率之间的关系，进而简化了[1]中导出Sasakian空间形式黎曼曲率张量的方法。

We give the related expression between the φ - sectional curvature and the sectional curvature of a Sasakian space form,then we simplify the method of the curvature tensor of the Sasakian space form deduced in [1]
