Abstract

The Hoft structure of the central extension of the Uq(sl(n)^)U_q \left( \widehat{sl\left( n \right) }\right) algebra is considered. The intertwine matrix induces new integrable spin chain models. We show the relation of these models and the biparametric spin chain slp,q(n)^\widehat{sl_{p,q} \left( n \right)} models. The cases n=2n=2 are n=3n=3 are discussed and for n=2n=2 we obtain the model of Dasgupta and Chowdhury . The case n=3n=3 is solved with nested Bethe ansatz method and it is showed the dependence of the Bethe equations in the second parameter introduced
