Abstract
The quantum nonlinear Schrodinger model with four-component fermions exhibi ts a Y(so(5)) symmetry when considered on an infinite interval. The constru cted generators of the Yangian are proved to satisfy the Drinfel'd formula and, furthermore, the RTT relation with the general form of a rational R-ma trix given by Yang-Baxterization associated with so(5) algebraic structure.
