Generalized discriminants, deformed Calogero-Moser-Sutherland operators and super Jack polynomialsIt is shown that the deformed Calogero-Moser-Sutherland (CMS) operators can be described as a restriction on certain affine subvarieties (called generalized discriminants) of the usual CMS operators for an infinite number of particles. The ideal of these varieties is shown to be generated by the Jack symmetric functions related to the Young diagrams with special geometry. A general structure of the ideals which are invariant under the action of the quantum CMS integrals is discussed in this context. The shifted super-Jack polynomials are introduced and combinatorial formulas for them and super-Jack polynomials are given.
