Conformal Newton–Hooke algebras, Niederer's transformation and Pais–Uhlenbeck oscillator
Dynamical systems invariant under the action of the l-conformal Newton–Hooke algebras are constructed by the method of nonlinear realizations. The relevant first order Lagrangians together with the corresponding Hamiltonians are found. The relation to the Galajinsky and Masterov [24] approach as wel...
