# nLab Jack polynomial

Jack polynomials (or Jack symmetric functions) form a class of symmetric functions $J_\lambda^\alpha$ labelled by a partition $\lambda$ and a parameter $\alpha$; by a result of I. G. Macdonald, they form a family of orthogonal polynomials. Jack polynomials can be defined as eigenfunctions of certain Laplac/Beltrami type operator coming in the theory of Calogero integrable systems and in random matrix theory. If $\alpha = 1$ the Jack polynomials become Schur polynomials.
