Computations for Coxeter arrangements and Solomon's descent algebra II: Groups of rank five and six
(Elsevier, 2013-01-08)
In recent papers we have refined a conjecture of Lehrer and Solomon expressing the character of a finite Coxeter group W acting on the graded components of its Orlik-Solomon algebra as a sum of characters induced from ...
On the quiver presentation of the descent algebra of the symmetric group
(Elsevier, 2013-03-18)
We describe a presentation of the descent algebra of the symmetric group G(n) as a quiver with relations. This presentation arises from a new construction of the descent algebra as a homomorphic image of an algebra of ...
