摘要
n - Yn空间的几何是由度规张量和扭转张量全等地生成的。本文得到了在n Yn空间中对d_ (r_)理论的类比,并研究了嵌入在该空间中的超曲面上测地线方程的推导,证明了在n Yn空间中曲率张量的结构具有特殊的特征,并得到了曲率张量的Ricci - Jacobi恒等式。我们建立了测地线方程有额外的和,这是由空间中存在扭转引起的。在n Yn空间中,测地线长度的变化与度规张量和扭转张量的乘积成正比。我们引入了nn -1超曲面的第二个基本张量παβ,并建立了它的结构,这与零扭转的黎曼空间有本质的不同。在此基础上,对曲率张量的结构进行了研究。
The Dаrbоuх Theory and Geodesics in the Metric Space with Torsion
The geometry of n Yn space is generated congruently together by the metric tensor and the torsion tensor. In the presented article has been obtained an analog of the Dаrbоuх theory in the n Yn space, also studied the deduction of the equation of the geodesic lines on the hypersurface that embedded in such spaces, showed that in the n Yn space the structure of the curvature tensor has special features and for curvature tensor obtained Ricci - Jacobi identity. We establish that the equations of the geodesics have additional summands, which are caused by the presence of torsion in the space. In n Yn space, the variation of the length of the geodesic lines is proportional to the product of metric and torsion tensors gijSjpk. We have introduced the second fundamental tensor παβ for the hypersurface n Yn-1 and established its structure, which is fundamentally different from the case of the Riemannian spaces with zero torsion. Furthermore, the results on the structure of the curvature tensor have been obtained.
