摘要: Based on zero-curvature equation, a series of new four-component nonlinear Schrodinger-type equations related to 3 × matrix problem are proposed by using the polynomial expansion spectral parameter. As two special reductions, generalized coupled Schrodinger equation and derivative obtained. And then, infinite conservation laws for each these constructed with aid Riccati-type equations.
