Some Systems of Multivariable Orthogonal Askey-Wilson Polynomials [chapter]

George Gasper, Mizan Rahman
Theory and Applications of Special Functions  
In 1991 Tratnik derived two systems of multivariable orthogonal Wilson polynomials and considered their limit cases. q-Analogues of these systems are derived, yielding systems of multivariable orthogonal Askey-Wilson polynomials and their special and limit cases.
