Einstein Relatively Easy - Energy-momentum tensor

WebNov 30, 2024 · Noether's first and second theorems both imply conserved currents that can be identified as an energy-momentum tensor (EMT). The first theorem identifies the EMT as the conserved current associated with global spacetime translations, while the second theorem identifies it as a conserved current associated with local spacetime translations. WebOne of the simplest energy-momentum tensors is the dust energy momentum tensor. This type of matter field consists of noninteracting incoherent matter.

(9.1.1) x ′ = γ ( v) ( x − v / c t), (9.1.2) t ′ = γ ( t − x v x / c 2), we can derive that energy and momentum behave in the same way, WebWe can express conservation of energy and momentum in terms of the stress-energy tensor. Recall that the physical meaning of the component Ttt is the energy density. To get the conservation laws, consider a small box with dimensions dx, dyand dz, and restrict our attention to the case of ’dust’, that is, a fluid trigonometria playlist
