摘要
研究了闭的具有相对迷向Landsberg曲率(即J+c(x)FI=0)的芬斯勒流形,并证明了若c(x)在流形上恒为正或恒为负,则该流形一定是黎曼流形。
In this paper,we study the closed Finsler manifold of relatively isotropic mean Landsberg curvature with J + c(x) FI = 0. We prove that if c(x) is always negative or positive on the manifold,then the Finsler manifold must be Riemannian manifold.
