Comment on Colliding null shells of matter [J. Math. Phys. 33, 1065 (1992)]

Abstract

The space-time created by the colliding null shells is combined with the metric of colliding waves. By this method evolution and collision of waves with exact back-reaction can be obtained in the de Sitter and Kasner space-times. (C) 2000 American Institute of Physics. [S0022- 2488(00)01811-9].
