Dimensionally Reduced Gravitational Chern-Simons Term and its Kink
arXiv:hep-th/0305117 · doi:10.1016/S0003-4916(03)00142-8
Abstract
When the gravitational Chern-Simons term is reduced from 3 to 2 dimensions, the lower dimensional theory supports a symmetry breaking solution and an associated kink. Kinks in general relativity bear a close relation to flat space kinks, governed by identical potentials.
