Field-dependent diffeomorphisms and the transformation of surface
charges between gauges
When studying gauge theories in the presence of boundaries, local symmetry transformations are typically classified as gauge or physical depending on whether the associated charges vanish or not. Here, we propose that physical charges should further be refined into "dynamical" or "kinematical" depending on whether they are associated with flux-balance …
