Comment on gr-qc/0309003: ``Comment on `Absence of trapped surfaces and singularities in cylindrical collapse' ''
Sergio M. C. V. Goncalves
Very recently, a ``Comment'' by Wang [gr-qc/0309003] on a paper by Gonçalves [Phys. Rev. D {\bf 65}, 084045 (2002)] appeared, claiming that Gonçalves' analysis of trapped surfaces…
Global symmetries: matter from geometry, hoop conjecture, and cosmic censorship
Sergio M. C. V. Goncalves
We show that four-dimensional Lorentzian metrics admitting a global spacelike Lie group of isometries, , which obey the Einstein equations for vacuum and certain…
Dark energy, dark matter and the Chaplygin gas
R. Colistete, J. C. Fabris, S. V. B. Goncalves +1
The possibility that the dark energy may be described by the Chaplygin gas is discussed. Some observational constraints are established. These observational constraints indicate th…
Anisotropic quantum cosmological models: a discrepancy between many-worlds and dBB interpretations
F. G. Alvarenga, A. B. Batista, J. C. Fabris +1
In the isotropic quantum cosmological perfect fluid model, the initial singularity can be avoided, while the classical behaviour is recovered asymptotically. We verify if initial a…
A Critical Look At Massive Scalar Field Collapse
Chris M. Chambers, Patrick R. Brady, Sergio M. C. V. Goncalves
We present the findings of an investigation of critical behavior in the collapse of spherically symmetric distributions of massive scalar field. Two distinct types of phase transit…
