特殊Finsler流形理论的整体方法

A Global Approach to the Theory of Special Finsler Manifolds

Nabil L. Youssef, S. H. Abed, A. Soleiman

摘要:

本文的目的是提供一个特殊的Finsler流形理论的整体介绍。我们在全球范围内引进和调查(或本质上,从局部坐标自由)许多最重要和最常用的特殊芬斯勒流形:局部闵可夫斯基,Berwald,Landesberg,一般Landesberg,$P$ -可约,$C$ -可约,半- $C$-可约,准- $C$ -可约,$P^{*}$ -Finsler,$C^{h}$-递归,$C^{v}$ -递归,$C^{0}$ -递归,$S^{v}$ -递归,$S^{v}$ -二阶递归,$C_{2}$ -类,$S_{3}$ -类,$S_{4}$ -类,$P_{2}$ -类,$R_{3}$ -类,$P$ -对称,$h$ -各向同性,标量曲率,常曲率,$p$ -标量曲率,$s$-$ps$-曲率.给出了这些特殊Finsler流形的整体定义。我们发现了所考虑的特殊Finsler流形的不同类型之间的各种关系,并在整体上证明了许多文献中已知的局部结果,得到了一些新的结果。作为副产品,我们得到了挠率张量场和曲率张量场的一些有趣的恒等式和性质。虽然我们的调查是完全全球性的,我们提供;比较的原因,附录提出了一个本地对应的我们的全球性的方法和本地定义的特殊芬斯勒空间考虑。

英文摘要:

The aim of the present paper is to provide a global presentation of the theory of special Finsler manifolds. We introduce and investigate globally (or intrinsically, free from local coordinates) many of the most important and most commonly used special Finsler manifolds: locally Minkowskian, Berwald, Landesberg, general Landesberg, $P$-reducible, $C$-reducible, semi-$C$-reducible, quasi-$C$-reducible, $P^{*}$-Finsler, $C^{h}$-recurrent, $C^{v}$-recurrent, $C^{0}$-recurrent, $S^{v}$-recurrent, $S^{v}$-recurrent of the second order, $C_{2}$-like, $S_{3}$-like, $S_{4}$-like, $P_{2}$-like, $R_{3}$-like, $P$-symmetric, $h$-isotropic, of scalar curvature, of constant curvature, of $p$-scalar curvature, of $s$-$ps$-curvature. The global definitions of these special Finsler manifolds are introduced. Various relationships between the different types of the considered special Finsler manifolds are found. Many local results, known in the literature, are proved globally and several new results are obtained. As a by-product, interesting identities and properties concerning the torsion tensor fields and the curvature tensor fields are deduced. Although our investigation is entirely global, we provide; for comparison reasons, an appendix presenting a local counterpart of our global approach and the local definitions of the special Finsler spaces considered.
