Comment on "What does the Letelier-Gal'tsov metric describe?"
G. Clement, D. V. Gal'tsov, P. S. Letelier
We show that the Letelier-Gal'tsov (LG) metric describing multiple crossed strings in relative motion does solve the Einstein equations, in spite of the discontinuity uncovered rec…
The Letelier-Gal'tsov spacetime revisited
G. Clement, D. V. Gal'tsov, P. S. Letelier
Contrary to a recent claim by Anderson ["The Mathematical Theory of Cosmic Strings", I.O.P. Publishing, Bristol 2003], we show that the Letelier-Gal'tsov metric does represent a sy…
Analytical approach to critical collapse in 2+1 dimensions
Gerard Clement, Alessandro Fabbri
We present a family of time-dependent solutions to 2+1 gravity with negative cosmological constant and a massless scalar field as source. These solutions are continuously self-simi…
Regularity and stability of electrostatic solutions in Kaluza-Klein theory
M. Azreg-Ainou, G. Clement, C. P. Constantinidis +1
We investigate the family of electrostatic spherically symmetric solutions of the five-dimensional Kaluza-Klein theory. Besides black holes and wormholes, a new class of geodesical…
Generating rotating fields in general relativity
Gerard Clement
I present a new method to generate rotating solutions of the Einstein-Maxwell equations from static solutions, give several examples of its application, and discuss its general pro…
Classical solutions of gravitating Chern-Simons electrodynamics
Gerard Clement
We discuss the reduction of gravitating Chern-Simons electrodynamics with two commuting Killing vectors to a dynamical problem with four degrees of freedom, and present regular par…
