A strong Henniart identity for reductive groups over finite fields

Abstract: In 1992, Henniart proved that supercuspidal representations for –adic GLn are determined by their character on so-called very regular elements.  This has been useful in many ways as it allows for convenient comparison between various constructions of supercuspidal representations for GLn.  We describe a version of this type of result which holds for (some) representations of reductive groups over finite fields.  This is joint work with Masao Oi.
