Abstract

We continue investigation of the universal weight function for the quantum affine algebra Uq(gl^N)U_q(\hat{\mathfrak{gl}}_N) started in arXiv:math/0610517 and arXiv:0711.2819. We obtain two recurrence relations for the universal weight function applying the method of projections developed in arXiv:math/0610398. On the level of the evaluation representation of Uq(gl^N)U_q(\hat{\mathfrak{gl}}_N) we reproduce both recurrence relations for the off-shell Bethe vectors calculated in arXiv:math/0702277 using combinatorial methods.
