摘要

The Heine-Stieltjes correspondence is extended and applied to solve Bethe ansatz equations of the SU(1,1) and SU(2) Gaudin models, from which the extended Heine-Stieltjes polynomial approach to these models is proposed. As examples for the application, exact solutions of the standard two-site Bose-Hubbard model and the standard pairing model are formulated from the corresponding polynomials.
