A basis of symmetric functions, which we denote by qλ(X; q, t), was introduced in the work of Ram and King and Wybourne in order to describe the irreducible characters of the Hecke algebras of type A. In this work we give combinatorial descriptions of the expansions of the functions qλ(X; q, t) in terms of the classical bases of symmetric functions and apply these results in determining the determinant of the character table of the Iwahori-Hecke algebras and in giving a generating function for certain permutation statistics. © 1996 Academic Press, Inc.
