Combinatorial Formula for the Hilbert Series of bigraded $S_n$-modules [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2009
We introduce a combinatorial way of calculating the Hilbert series of bigraded $S_n$-modules as a weighted sum over standard Young tableaux in the hook shape case.

A generalization of the Kostka-Foulkes polynomials [PDF]

open access: yes, 1998
Combinatorial objects called rigged configurations give rise to q-analogues of certain Littlewood-Richardson coefficients. The Kostka-Foulkes polynomials and two-column Macdonald-Kostka polynomials occur as special cases.

Macdonald Polynomials and Chromatic Quasisymmetric Functions [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2020
We express the integral form Macdonald polynomials as a weighted sum of Shareshian and Wachs' chromatic quasisymmetric functions of certain graphs. Then we use known expansions of these chromatic quasisymmetric functions into Schur and power sum symmetric functions to provide Schur and power sum formulas for the integral form Macdonald polynomials ...

Refined toric branes, surface operators and factorization of generalized Macdonald polynomials

open access: yesJournal of High Energy Physics, 2017
We find new universal factorization identities for generalized Macdonald polynomials on the topological locus. We prove the identities (which include all previously known forumlas of this kind) using factorization identities for matrix model averages ...

Canonical Basis and Macdonald Polynomials

open access: yesAdvances in Mathematics, 1998
In the basic representation of $U_q(\hat{sl}(2))$ realized via the algebra of symmetric functions we compare the canonical basis with the basis of Macdonald polynomials with $q=t^2$. We show that the Macdonald polynomials are invariant with respect to the bar involution defined abstractly on the representations of quantum groups. We also prove that the

Staircase Macdonald polynomials and the $q$-Discriminant [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
We prove that a $q$-deformation $\mathfrak{D}_k(\mathbb{X};q)$ of the powers of the discriminant is equal, up to a normalization, to a specialization of a Macdonald polynomial indexed by a staircase partition. We investigate the expansion of $\mathfrak{D}

On Hamiltonians for Kerov functions

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
Kerov Hamiltonians are defined as a set of commuting operators which have Kerov functions as common eigenfunctions. In the particular case of Macdonald polynomials, well known are the exponential Ruijsenaars Hamiltonians, but the exponential shape is not

A New Generalisation of Macdonald Polynomials [PDF]

open access: yesCommunications in Mathematical Physics, 2017
We introduce a new family of symmetric multivariate polynomials, whose coefficients are meromorphic functions of two parameters $(q,t)$ and polynomial in a further two parameters $(u,v)$. We evaluate these polynomials explicitly as a matrix product.

The Classification of All Singular Nonsymmetric Macdonald Polynomials

open access: yesAxioms, 2022
The affine Hecke algebra of type A has two parameters q,t and acts on polynomials in N variables. There are two important pairwise commuting sets of elements in the algebra: the Cherednik operators and the Jucys–Murphy elements whose simultaneous ...
