چکیده

There are representations of the type-A Hecke algebra on spaces polynomials in anti-commuting variables. Luque and author [Sém. Lothar. Combin. 66 (2012), Art. B66b, 68 pages, arXiv:1106.0875] constructed nonsymmetric Macdonald taking values arbitrary modules algebra. In this paper two ideas combined to define study aforementioned polynomials, other words, superpolynomials. The modules, their orthogonal bases properties first derived. terms standard Young tableau approach these correspond hook tableaux. details Dunkl-Luque theory particular application presented. is an inner product for which mutually orthogonal. squared norms determined. By using techniques Baker Forrester [Ann. Comb. 3 (1999), 159-170, arXiv:q-alg/9707001] symmetric built up from theory. Here ''symmetric'' means sense, not classical group sense. a concise formula norm minimal polynomial, some formulas anti-symmetric polynomials. For both there factorization when evaluated at special points.

The binomial formula for nonsymmetric Macdonald polynomials

The q-binomial theorem is essentially the expansion of (x − 1)(x − q) · · · (x − q) in terms of the monomials x. In a recent paper [O], A. Okounkov has proved a beautiful multivariate generalization of this in the context of symmetric Macdonald polynomials [M1]. These polynomials have nonsymmetric counterparts [M2] which are of substantial interest, and in this paper we establish nonsymmetric a...

Nonsymmetric Macdonald Polynomials and Demazure Characters

We establish a connection between a specialization of the nonsymmetric Macdonald polynomials and the Demazure characters of the corresponding affine Kac-Moody algebra. This allows us to obtain a representation-theoretical interpretation of the coefficients of the expansion of the specialized symmetric Macdonald polynomials in the basis formed by the irreducible characters of the associated fini...

Standard Bases for Affine Parabolic Modules and Nonsymmetric Macdonald Polynomials

We establish a connection between (degenerate) nonsymmetric Macdonald polynomials and standard bases and dual standard bases of maximal parabolic modules of affine Hecke algebras. Along the way we prove a (weak) polynomiality result for coefficients of symmetric and nonsymmetric Macdonald polynomials.

NONSYMMETRIC INTERPOLATION MACDONALD POLYNOMIALS AND gln BASIC HYPERGEOMETRIC SERIES

The Knop–Sahi interpolation Macdonald polynomials are inhomogeneous and nonsymmetric generalisations of the well-known Macdonald polynomials. In this paper we apply the interpolation Macdonald polynomials to study a new type of basic hypergeometric series of type gln. Our main results include a new q-binomial theorem, new q-Gauss sum, and several transformation formulae for gln series.

A Kato–lusztig Formula for Nonsymmetric Macdonald Polynomials

We prove a nonsymmetric analogue of a formula of Kato and Lusztig which describes the coefficients of the expansion of irreducible Weyl characters in terms of (degenerate) symmetric Macdonald polynomials as certain Kazhdan–Lusztig polynomials. We also establish precise polynomiality results for coefficients of symmetric and nonsymmetric Macdonald polynomials and a version of Demazure’s characte...
