Abstract
Analytical solutions for the Lipkin-Meshkov-Glick (LMG) model for some nont rivial limits are derived by using an infinite-dimensional algebraic approa ch based on the Bethe ansatz. Analytical expressions for eigenvalues and th e corresponding eigenfunctions of the Hamiltonian are obtained. Solutions f or the associated Bethe ansatz equations are given.
