Formulae relating the Bernstein and Iwahori-Matsumoto presentations of an affine Hecke algebra

Thomas J. Haines, Alexandra Pettet

Published 2002-01-18Version 1

We give explicit formulae for certain elements occurring in the Bernstein presentation of an affine Hecke algebra, in terms of the usual Iwahori- Matsumoto generators. We utilize certain minimal expressions for said elements and we give a sheaf-theoretic interpretation for the existence of these minimal expressions.
