论文摘要
在这篇简短的论文中,我们研究了Finsler几何形状中的对称协变量张量,这称为平均Berwald曲率。我们首先将纤维的几何形状作为鳍片歧管上切线球的子束的子束。然后,我们证明,如果平均Berwald曲率是沿纤维各向同性的,那么Berwald标量曲率沿纤维持续。
In this short paper, we study a symmetric covariant tensor in Finsler geometry, which is called the mean Berwald curvature. We first investigate the geometry of the fibres as the submanifolds of the tangent sphere bundle on a Finsler manifold. Then we prove that if the mean Berwald curvature is isotropic along fibres, then the Berwald scalar curvature is constant along fibres.
