Abstract
The orthogonality relations of multivariate Krawtchouk polynomials are discussed.
In case of two variables, the necessary and sufficient conditions of orthogonality
is given by Grünbaum and Rahman in [SIGMA 6 (2010), 090, 12 pages].
In this study, a simple proof of the necessary and sufficient condition of orthogonality
is given for a general case.
Key words:
multivariate orthogonal polynomial; hypergeometric function.
