energimomenteoritensor
The energimomenteoritensor, also known as the energy-momentum tensor, is a fundamental mathematical object in the theory of general relativity and classical field theory. It describes the distribution and flow of energy, momentum, and stress within a physical system. The tensor is a rank-2 tensor, meaning it has two indices and transforms according to the rules of tensor calculus under coordinate transformations.
In the context of general relativity, the energimomenteoritensor appears as the right-hand side of Einstein’s field
Gμν + Λgμν = (8πG/c⁴)Tμν
where Gμν is the Einstein tensor, Λ is the cosmological constant, gμν is the metric tensor, G is
The energimomenteoritensor is constructed differently depending on the type of matter or field being described. For
In quantum field theory, the energimomenteoritensor plays a crucial role in defining the energy and momentum
