Abstract

In this paper, we study Finsler warped product metrics. We obtain the differential equations that characterize Landsberg Finsler warped product metrics. By solving these equations, we obtain the expression of these metrics. Furthermore, we construct a class of almost regular Finsler warped product metrics F with the following properties: (1) F is a Landsberg metric; (2) F is not a Berwald metric; (3) F has zero flag curvature (or Ricci curvature).

具有零旗曲率的兰茨贝格-芬斯勒翘曲积度量

本文研究 Finsler 翘积度量。我们得到了表征兰茨贝格-芬斯勒翘曲积度量的微分方程。通过求解这些方程，我们得到了这些度量的表达式。此外，我们还构建了一类几乎正则的 Finsler 翘积度量 F，它们具有以下性质：（1）F 是一个 Landsberg 度量；（2）F 不是一个 Berwald 度量；（3）F 的旗曲率（或里奇曲率）为零。
