摘要

本文的目的是利用磁化奇异夸克物质(MSQM)研究f (R, T)引力理论背景下的Kaluza-Klein宇宙。为了得到场方程的精确解，我们假设了两种类型的体积展开:幂律和指数律体积展开。对能量条件的破坏进行了研究。所检查的模型的物理和几何性质也进行了深入的研究。

Accelerating Kaluza-Klein Universe in Modified Theory of Gravitation

The purpose of this paper is to study the Kaluza-Klein universe in the context of the f (R, T) gravity theory using magnetized strange quark matter (MSQM). To obtain exact solutions of field equations, we assume two types of volumetric expansion: power law and exponential law volumetric expansions. The violation of energy conditions has been studied. The physical and geometrical properties of the examined model have also been investigated thoroughly.

期刊介绍： Astrophysics (Ap) is a peer-reviewed scientific journal which publishes research in theoretical and observational astrophysics. Founded by V.A.Ambartsumian in 1965 Astrophysics is one of the international astronomy journals. The journal covers space astrophysics, stellar and galactic evolution, solar physics, stellar and planetary atmospheres, interstellar matter. Additional subjects include chemical composition and internal structure of stars, quasars and pulsars, developments in modern cosmology and radiative transfer.
