Center of the universal Askey–Wilson algebra at roots of unity
Inspired by a profound observation on the Racah–Wigner coefficients of Uq(sl2), the Askey–Wilson algebras were introduced in the early 1990s. A universal analog △q of the Askey–Wilson algebras was recently studied. For q not a root of unity, it is known that Z(△q) is isomorphic to the polynomial rin...
