{title2=$T^{\mu\nu}\mapsto T^{\mu\nu}+\partial_\rho B^{\rho\mu\nu}$}
If $B^{\rho\mu\nu}=-B^{\mu\rho\nu}$, commuting partial derivatives gives $\partial_\mu\partial_\rho B^{\rho\mu\nu}=0$. Such an improvement preserves conservation of a <stress-energy tensor> and changes integrated charges only by a spatial boundary term. The <Belinfante-Rosenfeld stress-energy tensor> is obtained through this type of improvement.
