Hi all,
Just a question i was wondering about. We know that in electrodynamics the Lagrangian is invariant under a gauge transformation of the potential, and this is equivalent to the law of conservation of charge.
Concerning relativity, what is the quantity that is conserved and are the gauge transformations Poincare transformations?
