1) Positive curvature on totally isotropic two-plane
全迷向正的截曲率
3) Ricci-isotropic curvature
迷向Ricci曲率
4) isotropic Berwald curvature
迷向Berwald曲率
1.
In this paper, we discuss the relation of the isotropic Berwald curvature for pojectively related Finsler metrics F and F, the necessary and sufficient condition that F is of isotropic S-curvature is obtained from the above result.
讨论了射影相关Finsler度量F与F的迷向Berwald曲率间的关系 ,并利用这种关系得到了一个射影相关下F具有迷向S 曲率的充分必要条
6) isotropic Landsberg curvature
迷向Landsberg曲率
1.
Firstly, considering that Finsler space with isotropic Landsberg curvature is related with Cartan torsion and Landsberg curvature,so it may turn to be related with mean Cartan torsion and mean Landsberg curvature, it gets Theorem 1.
L-可约的Finsler空间,若分别具有迷向Landsberg曲率、常曲率,则它能转化为C-可约的Finsler空间;在上述两种情形下,通过对比Landsberg曲率和Cartan挠率的关系,得到推论:L-可约的Finsler空间,若满足L∶0∶0+k(x,y)C=0,其中k(x,λy)=λ3k(x,y),则它是C-可约的。
