Abstract
In this paper we investigate the dynamics of the Lipkin-Meshkov-Glick model within the context of quantum algebras. For this purpose we obta in the equations of motion with the help of the time-dependent variati onal principle. To analyse the results, graphs for equi-energies, pote ntials and mean-square deviation of the J(z) operator have been plotte d. Modifications in the usual libration and rotational motions due to the introduction of quantum deformation are discussed.
