Richard Askey

Richard Askey, born on June fourth, nineteen thirty-three, was a distinguished American mathematician and university educator, celebrated for his profound contributions to the field of special functions.

In nineteen eighty-four, he introduced the Askey–Wilson polynomials in collaboration with James A. Wilson. This groundbreaking work positioned these polynomials at the pinnacle of the q-Askey scheme, a hierarchical organization of orthogonal polynomials of q-hypergeometric type.

Askey's influence extended beyond polynomials; he also formulated the Askey–Gasper inequality for Jacobi polynomials. This inequality played a crucial role in de Brange's renowned proof of the Bieberbach conjecture, further solidifying his legacy in mathematical research.
