Query: Dynamical realization of l-conformal Galilei algebra and oscillators   The method of nonlinear realizations is applied to the l-conformal Galilei
algebra to construct a dynamical system without higher derivative terms in the
equations of motion. A configuration space of the model involves coordinates,
which parametrize particles in d spatial dimensions, and a conformal mode,
which gives rise to an effective external field. It is shown that trajectories
of the system can be mapped into those of a set of decoupled oscillators in d
dimensions.
