On the SO(2,1) symmetry in General Relativity
Gaetano VilasiPatrizia Vitale
文献摘要
The role of the SO(2,1) symmetry in General Relativity is analyzed. Cosmological solutions of Einstein field equations invariant with respect to a space-like Lie algebra G_r, with r between 3 and 6 and containing so(2,1) as a subalgebra, are also classified.
