K. Mimachi et M. Noumi, AN INTEGRAL-REPRESENTATION OF EIGENFUNCTIONS FOR MACDONALDS Q-DIFFERENCE OPERATORS, Tohoku Mathematical Journal, 49(4), 1997, pp. 517-525
We give the eigenfunctions for Macdonald's q-difference operators in t
erms of q-Selberg type integrals. Our result can be applied not only t
o the case of Macdonald symmetric polynomials but also to the cases of
rational and meromorphic solutions.
