具有周期张力的宇宙弦圆环的演化

The evolution of circular loops of a cosmic string with periodic tension

Leilin Wang, Hongbo Cheng

摘要:

本文分别在Minkowski时空和Robertson-Walker宇宙中研究了具有周期张力的宇宙弦的圆环方程。我们发现,具有这种时变张力的宇宙弦环,如果其初始半径不够小,将演化为振荡而不是坍缩形成黑洞。

英文摘要:

In this paper the equation of circular loops of cosmic string with periodic tension is investigated in the Minkowski spacetime and Robertson-Walker universe respectively. We find that the cosmic string loops possessing this kind of time-varying tension will evolve to oscillate instead of collapsing to form a black hole if their initial radii are not small enough.
