摘要

我们证明了在具有消失曲率（特别是具有常旗曲率）的Finsler流形中，一些非黎曼几何结构是测地不变的，因此它们导出了一组非黎曼第一积分。这些第一积分的两个替代表达式可以根据平均Berwald曲率获得，也可以作为平均Cartan扭转和平均Landsberg曲率的函数获得。

First integrals for Finsler metrics with vanishing $\chi $-curvature

We prove that in a Finsler manifold with vanishing $\chi $-curvature (in particular with constant flag curvature) some non-Riemannian geometric structures are geodesically invariant and hence they induce a set of non-Riemannian first integrals. Two alternative expressions of these first integrals can be obtained either in terms of the mean Berwald curvature, or as functions of the mean Cartan torsion and the mean Landsberg curvature.
