Discrete complex reflection groups [PDF]

open access: bronzeCommunications in Mathematics, 2023
Here are reproduced slightly edited notes of my lectures on the classification of discrete groups generated by complex reflections of Hermitian affine spaces delivered in October of 1980 at the University of Utrecht.

On Coxeter Diagrams of complex reflection groups [PDF]

open access: greenTransactions of the American Mathematical Society, 2008
We study Coxeter diagrams of some unitary reflection groups. Using solely the combinatorics of diagrams, we give a new proof of the classification of root lattices defined over E

Complex reflection groups as differential Galois groups [PDF]

open access: greenACM Communications in Computer Algebra
Complex reflection groups comprise a generalization of Weyl groups of semisimple Lie algebras, and even more generally of finite Coxeter groups. They have been heavily studied since their introduction and complete classification in the 1950s by Shephard and Todd, due to their many applications to combinatorics, representation theory, knot theory, and ...

Centralisers, complex reflection groups and actions in the Weyl group E_6 [PDF]

open access: greenJournal of Homotopy and Related Structures, 2023
AbstractThe compact, connected Lie group $$E_6$$ E 6 admits two forms: simply connected and adjoint type. As we previously established, the Baum–Connes isomorphism relates the two Langlands dual forms, giving a duality between the equivariant K-theory of the ...

The Tutte Polynomial of Complex Reflection Groups [PDF]

open access: greenContributions to Discrete Mathematics, 2019
The story ”Tutte Polynomial of Reflection Group” begins in 2007 when Ardila computed the Tutte polynomials of the hyperplane arrangements associated to the symmetric groups Sym(n), and to the imprimitive groups $G(2,1,n)$ and $G(2,2,n)$. One year later, De Concini and Procesi computed the Tutte polynomials associated to the primitive groups $G28,G35,G36,

Complex Reflection Subgroups of Real Reflection Groups

open access: yesJournal of Algebra, 2000
Let \(V\) be an \(n\)-dimensional complex vector space, \(G\) an irreducible rank \(n\) complex, but not complexified, reflection group in \(V\), and \(W\) an irreducible rank \(2n\) finite real reflection group in \(_\mathbb{R} V\) such that ...

On partition algebras for complex reflection groups

open access: yesJournal of Algebra, 2007
This article is a valuable addition to the topic of partition algebras which was first introduced by Jones and Martin. The author concentrates on the partition algebra of the symmetric group. One of the main results that this paper comes up with is the explicit decomposition of the wreath product of \(\mathbb{Z}_r\) and \(S_n\), and decomposition of ...
