A Geometric Approach to Solomon's Descent Algebra
ABSTRACT: Solomon's descent algebra is an interesting non-commutative algebra
associated with a finite reflection group W. (The name comes from the case
where W is the symmetric group.) Bidigare discovered that it is closely
related to the semigroup algebras discussed in Lecture 1. I will explain
this connection and give some applications to the structure of the descent
algebra.
