In this chapter we study the energy-momentum tensor. After defining it from the Lagrangian formalism, we consider conservation equations in general, and apply it to the energy–momentum tensor. We find an ambiguity in the definition of the energy–momentum tensor, we fix it by considering the symmetric tensor, and we find the interpretation of the tensor'

Abstract The right-hand side of Einstein’s equation is supplied by the energy-momentum tensor, discussed in Chapter 12, which encodes the energy-momentum of matter fields. In flat spacetime the local conservation of energy-momentum can be expressed via the important constraint ▽⋅T=0. The same expression holds in curved spacetime.

Abstract Chapter 12 looks at the three most important energy–momentum tensors in general relativity, namely the energy–momentum tensors for incoherent matter or dust, a perfect fluid, and the electromagnetic field. The treatment is neither exhaustive nor complete, but is sufficient for generating the explicit expressions needed in future

In this chapter, we recapitulate the general properties of the energy momentum tensor (EMT). After the derivation of EMT according to the Noether’s theorem, we will discuss the physical meaning of the components of EMT. Then, we especially focus on the EMT in the gauge theory.
