Elastic thick shells in General Relativity
Irene Brito, J. Carot, E. G. L. R. Vaz
It is shown that exact spherically symmetric solutions to Einstein's Field Equations exist such that, over an open region of the spacetime, they are singularity free, satisfy the d…
Cylindrically symmetric inhomogeneous dust collapse with a zero expansion component
Irene Brito, M. F. A. da Silva, Filipe C. Mena +1
We investigate a class of cylindrically symmetric inhomogeneous -dust spacetimes which have a regular axis and some zero expansion component. For , we obtain new exact s…
Initial boundary-value problem for the spherically symmetric Einstein equations with fluids with tangential pressure
Irene Brito, Filipe C. Mena
We prove that, for a given spherically symmetric fluid distribution with tangential pressure on an initial spacelike hypersurface with a timelike boundary, there exists a unique, l…
Geodesics dynamics in the Linet-Tian spacetime with Lambda>0
Irene Brito, M. F. A. Da Silva, Filipe C. Mena +1
We analyse the geodesics' dynamics in cylindrically symmetric vacuum spacetimes with Lambda>0 and compare it to the Lambda=0 and Lambda<0 cases. When Lambda>0 there are two singula…
Cylindrically symmetric static solutions of the Einstein field equations for elastic matter
I. Brito, J. Carot, F. C. Mena +1
The Einstein field equations are derived for a static cylindrically symmetric spacetime with elastic matter. The equations can be reduced to a system of two nonlinear ordinary diff…
Geodesics dynamics in the Linet-Tian spacetime with Lambda<0
Irene Brito, M. F. A. da Silva, Filipe C. Mena +1
We investigate the geodesics' kinematics and dynamics in the Linet-Tian metric with Lambda<0 and compare with the results for the Levi-Civita metric, when Lambda=0. This is used to…
