WebNov 8, 2024 · The stress–energy tensor is defined as the tensor Tαβ of order two that gives the flux of the α th component of the momentum vector across a surface with constant xβ coordinate. In the theory of relativity, this momentum vector is taken as the four-momentum. In general relativity, the stress–energy tensor is symmetric, [1] T α β = T β α.
Web19.1 Energy-Momentum Tensor for Particles Because it is the fundamental object of interest for matter coupling, and also because it sheds some light on the eld energy-momentum tensor, we want to connect the T that comes from particles themselves to the eld version.
