| dc.description.abstract | This paper builds on the previous paper by the author, where a relationship between Zhedanov's algebra AW(3) and the double affine Hecke algebra (DAHA) corresponding to the Askey-Wilson polynomials was established. It is shown here that the spherical subalgebra of this DAHA is isomorphic to AW(3) with an additional relation that the Casimir operator equals an explicit constant. A similar result with q-shifted parameters holds for the antispherical subalgebra. Some theorems on centralizers and centers for the algebras under consideration will finally be proved as corollaries of the characterization of the spherical and antispherical subalgebra. | uk_UA |
| dc.description.sponsorship | This paper is a contribution to the Proceedings of the Seventh International Conference “Symmetry in Nonlinear Mathematical Physics” (June 24–30, 2007, Kyiv, Ukraine). I thank Jasper Stokman for suggesting me that the spherical subalgebra of the Askey–Wilson DAHA is related to Zhedanov’s algebra. I thank a referee for suggestions which led to inclusion of Remarks 2.1, 2.7 and 4.5. Some of the results presented here were obtained during the workshop Applications of Macdonald Polynomials, September 9–14, 2007 at the Banf f International Research Station (BIRS). I thank the organizers for inviting me. | uk_UA |
