Quiver Presentations for Descent Algebras of Exceptional Type
Goetz Pfeiffer
The descent algebra of a finite Coxeter group is a basic algebra, and as such it has a presentation as quiver with relations. In recent work, we have developed a combinatorial…
An algorithm for the unit group of the Burnside ring of a finite group
Robert Boltje, Goetz Pfeiffer
In this note we present an algorithm for the construction of the unit group of the Burnside ring of a finite group from a list of representatives of the conjugacy classe…
A Quiver Presentation for Solomon's Descent Algebra
Goetz Pfeiffer
The descent algebra is a subalgebra of the group algebra $\Q W$ of a finite Coxeter group , which supports a homomorphism with nilpotent kernel and commutative image in t…
The -modular descent algebras
M. D. Atkinson, G. Pfeiffer, S. J. van Willigenburg
The concept of descent algebras over a field of characteristic zero is extended to define descent algebras over a field of prime characteristic. Some basic algebraic structure of t…
Special involutions and bulky parabolic subgroups in finite Coxeter groups
Goetz Pfeiffer, Gerhard Roehrle
The conjugacy classes of so-called special involutions parameterize the constituents of the action of a finite Coxeter group on the cohomology of the complement of its complexified…
