摘要: This work reconsiders the formulation, due to Regge and Teitelboim, of phase space approach general relativity in asymptotically flat context, phrasing it language symplectic geometry. The necessary boundary conditions at spatial infinity are spelled out detail. Precise meaning is given statement that, as a result these conditions, Poincare group acts symmetry on relativity. situation compared with spi-picture Ashtekar Hansen, where larger asymptotic obtained.
