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…
Motion of Coloured Particles in Solitons of the O(3) Non-Linear Model
Rafael M. Fernandes, Patricio S. Letelier
We propose a consistent expression for the relativistic quadri-force referring to the classical interaction between a coloured particle and a scalar field multiplete. General aspec…
Numerical Simulation of General Relativistic Stellar Collapse
Cristian R. Ghezzi, Patricio S. Letelier
We present preliminar results and tests of a new general relativistic code to simulate the hydrodynamic collapse of a 21 solar masses star. We have assumed spherical symmetry and u…
