On the characters of unipotent representations of a semisimple p-adic group
Abstract: Let $G$ be a semisimple almost simple algebraic group defined and split over a nonarchimedean local field $K$ and let $V$ be a unipotent representation of $G(K)$ (for example, an Iwahori-spherical representation). We calculate the character of $V$ at compact very regular elements of $G(K)$. This is a joint work with George Lusztig.
