J. Barcelosneto et Tg. Dargam, CONSTRAINED ANALYSIS OF TOPOLOGICALLY MASSIVE GRAVITY, Zeitschrift fur Physik. C, Particles and fields, 67(4), 1995, pp. 701-705
We quantize the Einstein gravity in the formalism of weak gravitationa
l fields by using the constrained Hamiltonian method. Special emphasis
is given to the 2+1 spacetime dimensional case where a (topological)
Chern-Simons term is added to the Lagrangian.
