A Note on Krawtchouk Polynomials and Riordan Arrays
School of Science
Waterford Institute of Technology
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.
