Polynomials Associated with Equilibrium Positions in Calogero-Moser Systems

In a previous paper (Corrigan-Sasaki), many remarkable properties of classical Calogero and Sutherland systems at equilibrium are reported. For example, the minimum energies, frequencies of small oscillations and the eigenvalues of Lax pair matrices at equilibrium are all “integer valued”. The equilibrium positions of Calogero and Sutherland systems for the classical root systems (Ar, Br, Cr and Dr) correspond to the zeros of Hermite, Laguerre, Jacobi and Chebyshev polynomials. Here we define and derive the corresponding polynomials for the exceptional (E6, E7, E8, F4 and G2) and non-crystallographic (I2(m), H3 andH4) root systems. They do not have orthogonality but share many other properties with the above mentioned classical polynomials.
