XXZ-type Bethe ansatz equations and quasi-polynomials [PDF]
J. R. Li, V. TarasovWe study solutions of the Bethe ansatz equation for the XXZ-type integrable model associated with the Lie algebra sl_N. We give a correspondence between solutions of the Bethe ansatz equations and collections of quasi-polynomials. This extends the results of E.Mukhin and A.Varchenko for the XXX-type model and the trigonometric Gaudin model.View original: http://arxiv.org/abs/1210.2315
