1. Cordas cosmicas e vortices em relatividade geral : pertubações radiais de soluções estaticas e estacionarias
A linearized theory of the dynamics of small perturbations of certain cylindrically symmetric systems in general relativity is presented. Firstly, we deal with straight, static cosmic strings of finite thickness in the U(l) gauge theory coupled to the Einstein equations. Taking into account the asymptotic behavior of the solution and certain integral ide
