... Based on Noether’s theorem, construct the energy-momentum tensor for classical electromagnetism from the above Lagrangian. Note that the usual procedure does not result in a symmetric tensor. To remedy that, we can add to T µν a term of the form ∂λ K λµν , where K λµν is antisymmetric in its first t ...
