MORE ON GENERALIZED HEISENBERG-FERROMAGNET MODELS

We generalize the integrable Heisenberg ferromagnet model according to each Hermitian symmetric spaces and address various new aspects of th e generalized model. Using the first order formalism of generalized sp ins which are defined on the coadjoint orbits of arbitrary groups, we construct a Lagrangian of the generalized model from which we obtain t he Hamiltonian structure explicitly in the case of CP(N - 1) orbit. Th e gauge equivalence between the generalized Heisenberg ferromagnet and the nonlinear Schrodinger models is given. Using the equivalence, we find infinitely many conserved integrals of both models.
