Toward explicit Hilbert series of quasi-invariant polynomials in characteristic $p$ and $q$-deformed quasi-invariants

  title={Toward explicit Hilbert series of quasi-invariant polynomials in characteristic \$p\$ and \$q\$-deformed quasi-invariants},
  author={Frank Wang},
We study the spaces Qm of m-quasi-invariant polynomials of the symmetric group Sn in characteristic p. Using the representation theory of the symmetric group we describe the Hilbert series of Qm for n = 3, proving a conjecture of Ren and Xu [10]. From this we may deduce the palindromicity and highest term of the Hilbert polynomial and the freeness of Qm as a module over the ring of symmetric polynomials, which are conjectured for general n. We also prove further results in the case n = 3 that… 


Quasi-invariants of complex reflection groups
Abstract We introduce quasi-invariant polynomials for an arbitrary finite complex reflection group W. Unlike in the Coxeter case, the space of quasi-invariants of a given multiplicity is not, in
Quasi-Invariants in Characteristic p and Twisted Quasi-Invariants
The spaces of quasi-invariant polynomials were introduced by Feigin and Veselov, where their Hilbert series over fields of characteristic 0 were computed. In this paper, we show some partial results
Lectures on quasi-invariants of Coxeter groups and the Cherednik algebra
The paper an elementary introduction for non-specialists to the theory of quasi-invariants of Coxeter groups. The main object of study is the variety X_m of quasi-invariants for a finite Coxeter
Cherednik algebras and differential operators on quasi-invariants
We develop representation theory of the rational Cherednik algebra H associated to a finite Coxeter group W in a vector space h. It is applied to show that, for integral values of parameter `c', the
Quasi-invariants of Coxeter groups and m-harmonic polynomials
The space of m-harmonic polynomials related to a Coxeter group G and a multiplicity function m on its root system is defined as the joint kernel of the properly gauged invariant integrals of the
Action of Coxeter Groups on m-Harmonic Polynomials and Knizhnik—Zamolodchikov Equations
The Matsuo–Cherednik correspondence is an isomorphism from solutions of Knizhnik–Zamolodchikov equations to eigenfunctions of generalized Calogero–Moser systems associated to Coxeter groups G and a
Macdonald Polynomials and Algebraic Integrability
We construct explicitly (nonpolynomial) eigenfunctions of the difference operators by Macdonald in the case t=qk, k∈Z. This leads to a new, more elementary proof of several Macdonald conjectures,
Commutative rings of partial differential operators and Lie algebras
We give examples of finite gap Schrödinger operators in the two-dimensional case.
