Abstract
The massless Thirring model associated with SO(5) is solved in terms of the local U(1) symmetry. The local U(1) symmetry is related to q-deformation o f four-component field operators due to the nonlinear interaction for diffe rent internal degrees of freedom. The Bethe ansatz wavefunction is also dis cussed. In addition, the local U(1) symmetry in the Yangian associated with SO(5)(Y(SO(5))) is explored.
