Remarks on Galilean electromagnetism
arXiv:2601.09761 · doi:10.1016/j.physletb.2026.140536
Abstract
It is shown that equations describing the Galilean electromagnetism in the presence of sources hold invariant under the l-conformal Galilei group for an arbitrary (half)integer parameter l. The group contains transformations which link an inertial frame of reference to those moving with constant accelerations of order up to 2l-1, thus pointing at potential dynamical instability.
