A note on Krawtchouk polynomials and Riordan arrays

Zbl   EuDML
We study links between Krawtchouk polynomials and Riordan arrays of both the ordinary kind and the exponential kind. We derive summation formulas for values of the Krawtchouk polynomials using the A-sequences of the Riordan arrays.
Keywords: krawtchouk polynomials, orthogonal polynomials, riordan arrays, integer sequences
