Abstract

This paper aims at investigating pseudo Z symmetric space-times (PZS)₄ admitting a type of semi-symmetric nonmetric connection (ssnmc). At first, we scrutinize the impact of a ssnmc on Lorentzian manifolds and establish a nontrivial example. Then, we examine the general properties of (PZS)₄ space-times and express the physical consequences of this space-time. Among others, it is demonstrated that a (PZS)₄ space-time admitting a ssnmc whose Ricci tensor vanishes becomes a GRW space-time as well as a perfect fluid space-time and a purely electric space-time under a certain condition.

伪Z对称时空允许一类半对称非度量连接

本文旨在研究允许一类半对称非度量连接（ssnmc）的伪Z对称时空（PZS）4。首先，我们仔细研究了ssnmc对洛伦兹流形的影响，并建立了一个非平凡的例子。然后，我们考察了（PZS）4时空的一般性质，并表达了这种时空的物理后果。其中，证明了在一定条件下，存在Ricci张量消失的ssnmc的（PZS）4时空可以成为GRW时空、完美流体时空和纯电时空。

期刊介绍： Reports on Mathematical Physics publish papers in theoretical physics which present a rigorous mathematical approach to problems of quantum and classical mechanics and field theories, relativity and gravitation, statistical physics, thermodynamics, mathematical foundations of physical theories, etc. Preferred are papers using modern methods of functional analysis, probability theory, differential geometry, algebra and mathematical logic. Papers without direct connection with physics will not be accepted. Manuscripts should be concise, but possibly complete in presentation and discussion, to be comprehensible not only for mathematicians, but also for mathematically oriented theoretical physicists. All papers should describe original work and be written in English.
