Bethe Ansatz and Quantum Davey-Stewartson 1 System with Multicomponent   in Two Dimensions
  The quantum 2-component DS1 system was reduced to two 1D many-body problems with $\delta-$function interactions, which were solved by Bethe ansatz. Using the ansatz in ref.[1] and introducing symmetric and antisymmetric Young operators of the permutation group, we obtain the exact solutions for the system.
