Dust cloud and energy momentum tensor

WebMar 27, 2024 · We derive the effective energy-momentum tensor described by the quadratic terms of the gravitational and the matter perturbations. We show that the second-order effective energy-momentum tensor is gauge dependent. We impose three gauge conditions (longitudinal, spatially-flat, and comoving gauges) for dust and radiation.

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. http://einsteinrelativelyeasy.com/index.php/general-relativity/78-the-energy-momentum-tensor
