Symmetries of Post-Galilean Expansions
Joaquim Gomis, Axel Kleinschmidt, Jakob Palmkvist, Patricio Salgado-Rebolledo
Abstract
In this Letter we study an infinite extension of the Galilei symmetry group in any dimension that can be thought of as a nonrelativistic or post-Galilean expansion of the Poincaré symmetry. We find an infinite-dimensional vector space on which this generalized Galilei group acts and usual Minkowski space can be modeled by our construction. We also construct particle and string actions that are invariant under these transformations.
