Deformed MacdonaldRuijsenaars Operators and Super Macdonald Polynomials
Abstract
It is shown that the deformed MacdonaldRuijsenaars operators can be described as the restrictions on certain affine subvarieties of the usual Macdonald Ruijsenaars operator in infinite number of variables. The ideals of these varieties are shown to be generated by the Macdonald polynomials related to Young diagrams with special geometry. The super Macdonald polynomials and their shifted version are introduced; the combinatorial formulas for them are given.
