An explicit formula for symmetric polynomials related to the eigenfunctions of Calogero-Sutherland models

We review a recent construction of an explicit analytic series representation for symmetric polynomials which up to a groundstate factor are eigenfunctions of Calogero– Sutherland type models. We also indicate a generalisation of this result to polynomials which give the eigenfunctions of so-called ‘deformed’ Calogero–Sutherland type models.
