Cosmic String in the BTZ Black Hole Background with Time-Dependant Tension
J. Sadeghi, H. M. Farahani, B. Pourhassan +1
In this paper, we study the equation of circular loops with time-dependant tension in the BTZ black hole background. We obtain various cases where cosmic string loops finally colla…
