| 摘 要： | The invariant Randers metrics on four dimensional Lie groups is studied. On the one hand, four dimensional nilpotent Lie groups with Randers metrics of Berwald type are two step nilpotent. And then prove that there exist invariant Randers metrics on four dimensional nilpotent Lie groups, which admit infinitely many homogeneous geodesics through the identity element. |
| 关 键 词： | Randers metrics homogeneous geodesics |
