The circular loop equation of a cosmic string with time-varying tension
Hongbo Cheng, Yunqi Liu
The equation of circular loops of cosmic string with time-dependent tension is studied in the Minkowski spacetime and Robertson-Walker universe. We find that, in the case where the…

The circular loop equation of a cosmic string with time-varying tension in de Sitter spacetimes
Yunqi Liu, Hongbo Cheng
In this work the equation of circular loops of cosmic string possessing time-dependent tension is studied in the de Sitter spacetime. We find that the cosmic string loops with init…
