Cosmological constant influence on cosmic string spacetime
arXiv:0812.4729 · doi:10.1103/PhysRevD.67.103504
Abstract
We investigate the line element of spacetime around a linear cosmic string in the presence of a cosmological constant. We obtain the metric and argue that it should be discarded because of asymptotic considerations. Then a time dependent and consistent form of the metric is obtained and its properties are discussed.
