Abstract Any finite reflection group G admits a distinguished basis of G -invariants canonically attached to a certain system of invariant differential equations. We determine it explicitly for groups of types A , B , D , and I in a systematic way. 

Dunkl Operators and Canonical Invariants of Reflection Groups

Using Dunkl operators, we introduce a continuous family of canonical invariants of finite reflection groups. We verify that the elementary canonical invariants of the sym- metric group are

On regularity of finite reflection groups

Abstract: We define a concept of “regularity” for finite unitary reflection groups, and show that an irreducible finite unitary reflection group of rank greater than 1 is regular if and only if it is

Canonical Systems of Basic Invariants for Unitary Reflection Groups

Abstract It is known that there exists a canonical system for every finite real reflection group. In a previous paper, the first and the third authors obtained an explicit formula for a canonical

Polynomial Invariants and Harmonic Functions Related to Exceptional Regular Polytopes

TLDR
Using this result, the solution space of functions satisfying a mean value property related to the exceptional regular polytopes, namely, the icosahedron and dodecahedron in three dimensions and the 24-cell, 600- cell, and 120-cell in four dimensions is determined.

Invariants of Finite Reflection Groups and the Mean Value Problem for Polytopes

Let P be an n‐dimensional polytope admitting a finite reflection group G as its symmetry group. Consider the set HP(k) of all continuous functions on Rn satisfying the mean value property with

Polytopes, Invariants and Harmonic Functions

. The classical harmonic functions are characterized in terms of the mean value property with respect to the unit ball. Replacing the ball by a polytope, we are led to the notion of polyhedral har

Basic sets of invariant polynomials for finite reflection groups

A basic net of invariant polynomials is explicitly given for each non-factorizable finite reflection group.

Some questions in the geometric theory of invariants of groups generated by orthogonal and oblique reflections

This paper continues the general survey in [30]. We consider the problem of finding in explicit form the basic invariants of symmetry groups of regular polyhedra and Gosset polyhedra. We study the

Invariants of Finite Reflection Groups

Let us define a reflection to be a unitary transformation, other than the identity, which leaves fixed, pointwise, a (reflecting) hyperplane, that is, a subspace of deficiency 1, and a reflection

Finite Unitary Reflection Groups

Any finite group of linear transformations on n variables leaves invariant a positive definite Hermitian form, and can therefore be expressed, after a suitable change of variables, as a group of
