Belinfante–Rosenfeld stress–energy tensor
text:
In mathematical physics, the Belinfante–Rosenfeld tensor is a modification of the stress–energy tensor that is constructed from the canonical stress–energy tensor and the spin current so as to be symmetric yet still conserved. In a classical or quantum local field theory, the generator of Lorentz transformations can be written as an integral of a local current Here T μ λ is the canonical stress–energy tensor satisfying ∂ μ T μ λ = 0 , and S μ ν λ is the contribution of the intrinsic (spin) angul
