Elementary properties of the Koornwinder-Macdonald multivariable Askey-Wilsonpolynomials are discussed. Studied are the orthogonality, the differenceequations, the recurrence relations, and the orthonormalization constants forthese polynomials. Essential in our approach are certain commuting differenceoperators simultaneously diagonalized by the polynomials.Comment: 5 pages, REVTeX with amssym
