Nonsymmetric Macdonald polynomials are multivariate polynomials which satisfy an orthogonality condition. They were introduced by Macdonald, after which Cherednik, Knop, Sahi and others developed the theory further. In this talk I will discuss how these functions form natural counterparts in many ways to the more well-known symmetric Macdonald polynomials. Then I will show how combinatorial results of a few years ago, joint with M. Haiman and N. Loehr, on the symmetric Macdonald polynomials, together with past results of Knop and Sahi on nonsymmetric Jack polynomials, led experimentally to a conjectured combinatorial formula for nonsymmetric poloynomials, which Haiman, Loehr and I have since proved.
