论文摘要
时空是4维连接的Lorentzian歧管。在本文中，我们将时空定义的Levi-civita连接扩展到半对称性的非金属连接，并结束由度量（1.1）与半对称非金属连接所接受的几何结构。显然，莫里斯 - thorne时空是RICCI广义的假性对称性，RICCI广义投射性假性对称性，并且具有复发性的共形2型，等等。它也是Einstein的2级和3- Quasi-inensteinerold的爱因斯坦歧管。
Spacetime is a 4-dimensional connected Lorentzian manifold. In this paper, we extend the Levi-Civita connection in the definition of spacetime to the semi-symmetric non-metric connection and conclude geometric structures admitted by the metric (1.1) with the semi-symmetric non-metric connections. Obviously, Morris-Thorne spacetime is Ricci generalized pseudosymmetry, Ricci generalized projectively pseudosymmetry, and has conformal 2-forms that are recurrent, etc. It also is an Einstein manifold of level 2 and 3-quasi-Einstein manifold.
