ON THE GRAVITATIONAL CHERN-SIMONS ACTION AS ENTROPY FUNCTIONAL FOR THREE-MANIFOLDS

摘要

We determine the more general geometrical flow in the space of metrics corresponding to the steepest descent for the three- dimensional gravitational Chern-Simons action, extending the results considered recently by ?zgür Kisisel et al. [Class. Quantum Grav. 25 (2008) 165019].
