我们将研究五维标量-向量和标量-卡布-雷蒙模型的宇宙学意义。特别地,将得到该模型的一组新的Bianchi I型幂律解析解。宇宙无毛猜想可以被证明在标量-矢量和标量-卡尔布-雷蒙耦合的存在下被打破。在幂律解存在的情况下,Kalb-Ramond场的影响将被明确地显示出来。然而,我们也将证明,幻场的存在确实会破坏相应的Bianchi I型幂律暴胀解的稳定性。
We will study the cosmological implications of the five dimensional scalar–vector and scalar-Kalb–Ramond model. In particular, a new set of Bianchi type I power-law analytic solution will be obtained for this model. The cosmic no-hair conjecture can be shown to break down in the presence of the scalar–vector and scalar-Kalb–Ramond couplings. The effect of the Kalb–Ramond field in the presence of the power-law solution will be shown explicitly. We will also show that the presence of a phantom field does, however, destabilize the corresponding Bianchi type I power-law inflationary solutions.
