\titleofpresentation{Coxeter Length}

\presenter{Peter Rowley}


 The notion of the length of an element in a Coxeter group frequently plays an
important role in understanding various aspects of the Coxeter
group. Indeed, there are many results concerning Coxeter groups which
are proved by induction on the length of elements. In this talk we
introduce a length function on subsets of a Coxeter group (which
generalizes the length function on elements) and investigate some of
its properties.
