Abstract

Let $c$ be the family of irreducible representations of a Weyl group $W$ corresponding to a two-sided cell of $W$ . We define a subset $A_c$ of $c$ which contains the special representation of $W$ in $c$ and is in canonical bijection with the set of constructible representations of $W$ attached to $c$ .
