具有λ项的暴涨Brans-Dicke宇宙学中的切变和涡度
Shear and Vorticity in Inflationary Brans-Dicke Cosmology with Lambda-Term
摘要：
我们在Brans-Dicke宇宙学中找到了一个包含时变切变和涡度的宇宙学项的指数暴胀解。我们发现当β < 0时，标量场和标度因子呈指数增长，而剪切、涡度、能量密度、宇宙压力和宇宙学项呈指数衰减。
英文摘要：
We find a solution for exponential inflation in Brans-Dicke cosmology endowed with a cosmological term, which includes time-varying shear and vorticity. We find that the scalar field and the scale factor increase exponentialy while shear, vorticity, energy density, cosmic pressure and the cosmological term decay exponentialy for beta < 0, where beta is defined in the text.
