Double Affine Hecke Algebras for the Spin Symmetric Group
We introduce a new class (in two versions, Au and Bu) of rational double affine Hecke algebras (DaHa) associated to the spin symmetric group. We establish the basic properties of the algebras, such as PBW and Dunkl representation, and connections to Nazarov’s degenerate affine Hecke algebra and to a new degenerate affine Hecke algebra introduced here. We formulate a precise connection between t...
متن کاملAffine Stanley Symmetric Functions
We define a new family F̃w(X) of generating functions for w ∈ S̃n which are affine analogues of Stanley symmetric functions. We establish basic properties of these functions such as their symmetry and conjecture certain positivity properties. As an application, we relate these functions to the k-Schur functions of Lapointe, Lascoux and Morse as well as the cylindric Schur functions of Postnikov. ...
متن کاملAffine Normalization of Symmetric Objects
A new method of normalization is used for the construction of the affine moment invariants. The affine transform is decomposed into translation, scaling, stretching, two rotations and mirror reflection. The object is successively normalized to these elementary transforms by means of low order moments. After normalization, other moments of normalized object can be used as affine invariant featur...
متن کاملAffine Projections of Symmetric Polynomials
In this paper we introduce a new model for computing polynomials a depth 2 circuit with a symmetric gate at the top and plus gates at the bottom, i.e the circuit computes a symmetric function in linear functions Sd m(`1; `2; :::; `m) (Sd m is the d’th elementary symmetric polynomial in m variables, and the `i’s are linear functions). We refer to this model as the symmetric model. This new model...
متن کاملA bijection on core partitions and a parabolic quotient of the affine symmetric group
Let l, k be fixed positive integers. In [1], the first and third authors established a bijection between l-cores with first part equal to k and (l − 1)-cores with first part less than or equal to k. This paper gives several new interpretations of that bijection. The l-cores index minimal length coset representatives for f Sl/Sl where f Sl denotes the affine symmetric group and Sl denotes the fi...
