Abstract
Vector fields ξi, corresponding to the Poincaré group generators (infinitesimal translations and rotations) are defined by first-order differential conditions. These equations have nontrivial solutions in an arbitrary torsionless Riemannian space, and can be considered as a generalization of the definition of translations and rotations in flat space. The equations for translations can be integrated. For a space with the Minkowski topology, if the boundary conditions at infinity are shown so that the space is asymptotically flat, the solution is unique. The vector fields ξi specify a physical system as a whole.
