From generalized Fourier transforms to spectral curves for the Manakov hierarchy. II. Spectral curves for the Manakov hierarchy

The hierarchies of multicomponent models of Manakov type are briefly outlined. Many of them have important applications n nonlinear optics. Next, we develop a method for calculating the spectral curves for the multiphase solutions of these equations. We discuss also other multicomponent generalization of Manakov system to which our method can be extended.
