Abstract In the present paper we introduce a semi-quasi-Einstein manifold from a semi symmetric metric connection. Among others, the popular Schwarzschild and Kottler spacetimes are shown to possess this structure. Certain curvature conditions are studied in such a manifold with a Killing generator.

关于半准爱因斯坦流形

摘要 在本文中,我们从半对称度量连接中引入了一个半准爱因斯坦流形。其中,流行的 Schwarzschild 和 Kottler 时空被证明具有这种结构。在这种带有 Killing 发生器的流形中研究了某些曲率条件。
