| 摘要: | 作为著名Hilbert第四问题的正则性情况, 局部射影平坦Finsler度量的研究一直是Finsler几何中的重要问题. 文中主要讨论一类多项式类型的广义-度量, 并得到了此类度量是局部射影平坦度量的等价条件, 以及利用此等价条件构造了一些新的非闵可夫斯基的局部射影平坦的广义-度量 |
| Abstract: | As the regular case of famous Hilbert’s fourth problem, the study of projectively flat Finsler metric is an important problem in Finsler geometry. In this paper, we discuss and prove equivalent conditions for a class of polynomial type, projectively flat general -metrics. Using the equivalent conditions, we construct some new non-Minkowskian projectively flat general -metrics |
