Effects of inflation on a cosmic string loop population

摘要: We study the evolution of simple cosmic string loop solutions in an inflationary universe. show, for particular case circular loops, that periodic do exist a de Sitter universe, below critical radius R{sub c}H=1/2. On other hand, larger loops freeze comoving coordinates, and we explicitly show they can survive more e-foldings inflation than pointlike objects. discuss implications these findings survival realistic during general characteristics post-inflationary networks. also consider analogous domain walls, which is c}H=2/3.
