摘要

我们描述了洛伦兹流形，这些流形接纳了具有零扭转分量和非零矢量分量的平行扭转的度量连接。我们还描述了洛伦兹流形，它接纳了具有封闭平行倾斜对称扭转的度量连接。

Lorentzian connections with parallel twistor-free torsion

We describe Lorentzian manifolds that admit metric connections with parallel torsion having zero twistorial component and non-zero vectorial component. We also describe Lorentzian manifolds admitting metric connections with closed parallel skew-symmetric torsion.
