Very recently, a ``Comment'' by Wang [gr-qc/0309003] on a paper by Gon\c{c}alves [Phys. Rev. D {\bf 65}, 084045 (2002)] appeared, claiming that Gon\c{c}alves' analysis of trapped surfaces in certain kinds of cylindrical spacetimes was incomplete. Specifically, Wang claims to have found a coordinate extension of the spacetime used by Gon\c{c}alves (the Einstein-Rosen spacetime) which contains trapped surfaces; in addition, Wang also claims that some such trapped surfaces are apparent horizons…

Comment on 'Absence of trapped surfaces and singularities in cylindrical collapse'

- Physics
- 2005

Recently, the gravitational collapse of an infinite cylindrical thin shell of matter in an otherwise empty spacetime with two hypersurface orthogonal Killing vectors was studied by Goncalves [Phys.…

A new proof for non-occurrence of trapped surfaces and information paradox

- Physics

We present here a very simple, short and new proof which shows that no trapped surface is ever formed in spherical gravitational collapse of isolated bodies. Although this derivation is of purely…

Unpolarized radiative cylindrical spacetimes: trapped surfaces and quasilocal energy

- Physics, Mathematics
- 2002

We consider the most general vacuum cylindrical spacetimes, which are defined by two global, spacelike, commuting, non-hypersurface-orthogonal Killing vector fields. The cylindrical waves in such…

Asymptotes of solutions of a perfect fluid coupled with a cosmological constant in four-dimensional spacetime with toroidal symmetry

- Mathematics, Physics
- 2006

AbstractAsymptotes of solutions of a perfect fluid when coupled with a cosmological constant in four-dimensional spacetime with toroidal symmetry are studied. In particular, it is found that the…

No-horizon theorem for spacetimes with spacelike G1 isometry groups

- Mathematics

We consider four-dimensional spacetimes (M, g) which obey the Einstein equations G = T and admit a global spacelike isometry group. By means of dimensional reduction and local analysis on the reduced…

Gravitational collapse in a cylindrical symmetric vacuum space-time and the naked singularity

- Physics, Mathematics

Abstract.We construct a cylindrical symmetry vacuum solution of the Einstein field equations, regular everywhere except on the symmetry axis where it possesses a naked curvature singularity. The…

ABSENCE OF APPARENT HORIZONS IN TRANSLATIONALLY-INVARIANT EINSTEIN–MAXWELL SPACETIMES

- Physics, Mathematics
- 2004

We show that (3+1) Einstein–Maxwell spacetimes admitting a global, spacelike, one-parameter Lie group of isometries of translational type cannot contain apparent horizons. The only assumption made is…

Dressing a Naked Singularity: an Example

- Physics, Mathematics
- 2010

Considering the evolution of a perfect fluid with self-similarity of the second kind, we find that an initial naked singularity can be trapped by an event horizon due to collapsing matter. The fluid…

A NOTE ON THE CYLINDRICAL COLLAPSE OF COUNTER-ROTATING DUST

- Mathematics
- 2002

We find analytical solutions describing the collapse of an infinitely long cylindrical shell of counter-rotating dust. We show that — for the classes of solutions discussed herein — from regular…
