摘要
We start from a Lorentzian action in a deformed light-cone background and applying the method of null reduction leads to a Carrollian action in one lower spacetime dimensions. We also identify the correct light-cone definitions of the symmetry generators and their dynamical forms in terms of the fields and take the limit. It is observed that these generators produce the known kinematic Carrollian conformal algebraic commutation relations.
