摘要
证明了在非均匀球对称的Tolman-Bondi时空中,应用Brans-Dicke理论,当作为外场的B-D标量场是非均匀的,且将其视为时空挠率的挠率势时,选取合适的拉氏作用量,则极早期宇宙将以指数幂律倍增的形式发生暴涨。
Brans-Dicke theory is employed in inhomogeneous spherically symmetric Tolman-Bondi space-time.when scalar field as outer field is inhomogeneous and is regarded as torsion potential of space-time's torsion, the exponential multiplying power-law inflation may occur in the very early stage of the universe.
