Assume G is a finite reductive group defined over a field of good characteristic. In 1986 Kawanaka introduced a family of (ordinary) representations of G called GGG Rs. These are indexed by the unipotent conjugacy classes of G and elucidate an interesting, and somewhat surprising, relationship between the unipotent conjugacy classes and the irreducible characters of G. In this talk we discuss a programme concerned with determining the decomposition of the GGG Rs into irreducible characters. Such information should help us to further levy the interesting relationship between conjugacy classes and characters.
