The correspondence between the thermodynamic energy equation satisfied by a closed comoving volume and conservation energy-momentum tensor of matter inside is extended to more general system with an arbitrary cosmological horizon heat source. consisting internal could be conserved defining surface on horizons. Therefore, can always consistent for such system. On other hand, from perspective cla...

In the Poincaré gauge theory of gravity, which has been formulated on the basis of a principal fiber bundle over the space-time manifold having the covering group of the proper orthochronous Poincaré group as the structure group, we examine the tensorial properties of the dynamical energy-momentum density Tk μ and the “spin” angular momentum density Skl μ of the gravitational field. They are bo...
