Query: On the definition of unipotent representations   Let G be a connected reductive group over a finite field F_q. A map from
irreducible representations of G(F_q) to semisimple classes in the dual group
was defined by a cohomological method by Deligne and the author in 1976. Here
we show that when q is large enough this map has an alternative
(non-cohomological) definition.
