摘要：
Using local SO(1,2) transform and general displacement transform, We obtain generally covariant conservation laws of angular -momentum and energy-momentum for ISO(1,2) Chern-Simons gravity. The currents have also superpotentials and are therefore identically conserved. The structure of the superpotentials are simpler than those in the conventional SO(1,2) topologically massive gravity (TMG). The reasonableness of the definitions may be supported by the correct energy momentum and angular-momentum for Cho-Lee's exact solution. (C) 1997 Elsevier Science B.V.
