Let W be a finite Coxeter group in a Euclidean vector space V, and m a W-invariant Z_+-valued function on the set of reflections in W. Chalyh and Veselov introduced in an interesting algebra Q_m, called the algebra of m-quasiinvariants for W. This is the algebra of quantum integrals of the rational Calogero-Moser system with coupling constants m. In a recent paper math-ph/0105014, Feigin and Veselov proposed a number of interesting conjectures concerning the structure of Q_m, and verified them… 

Cohen–Macaulay modules over the algebra of planar quasi–invariants and Calogero–Moser systems

In this paper, we study properties of the algebras of planar quasi‐invariants. These algebras are Cohen–Macaulay and Gorenstein in codimension one. Using the technique of matrix problems, we classify

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

Cohen-Macaulay modules over surface quasi-invariants and Calogero-Moser systems

In this paper, we study algebras of surface quasi-invariants and prove that they are Cohen-Macaulay and Gorenstein in codimension one. Using the technique of matrix problems, we classify all

Graded Cherednik Algebra And Quasi-Invariant Differential Forms

Given a finite Coxeter group W acting on its finite dimensional reflection representation V, we consider the ring D(ΩV)[RTIMES]W of equivariant differential operators on differential forms on V. After

A Class of Baker–Akhiezer Arrangements

We study a class of arrangements of lines with multiplicities on the plane which admit the Chalykh–Veselov Baker–Akhiezer function. These arrangements are obtained by adding multiplicity one lines in

Cyclotomic double affine Hecke algebras

We show that the partially spherical cyclotomic rational Cherednik algebra (obtained from the full rational Cherednik algebra by averaging out the cyclotomic part of the underlying reflection group)

Some New Methods in the Theory of m-Quasi-Invariants

TLDR
A new approach to the study of m-quasi-invariants is introduced which leads to an interesting free module of triplets of polynomials in the elementary symmetric functions e1;e2;e3 which explains certain observed properties of S3 m- Quasi-Invariants.
