โฆ Synopsis
Properties of the q-ultraspherical polynomials for q being a primitive root of unity, are derived using a formalism of the soq(3) algebra. The orthogonality condition for these polynomials provides a new class of trigonometric identities representing discrete finite-dimensional analogues of q-beta integrals of Ramanujan.

We consider various specializations of the untwisted quantum affine algebras at roots of unity. We define and study the q-characters of their finite-dimensional representations.
We give some applications of our recent work [10] about Hall-Littlewood functions at roots of unity. In particular, we prove the two conjectures of N. Sultana [17] on specializations of Green polynomials, and we generalize classical results concerning characters of the symmetric group induced by max
