...While understanding the usual representation theory of Un(q) is a wild problem, Andr e [1, 2, 3, 4] and Yan [
23
, 24] constructed a natural approximation to the representation theory that leads to a more computable theory...
...These computations require knowledge of tensor product results that were previously done by Andr e [1] for large prime and by Yan [
23
] for arbitrary primes...

Superinduction for pattern groups
...While describing the conjugacy classes or irreducible characters of Un(Fq) is a wellknown wild problem, Carlos Andr´e [1, 2, 4] and Ning Yan [
17
, 18] have shown that certain unions of conjugacy classes (hereafter superclasses) and certain characters (hereafter supercharacters) have an elegant theory that is rich enough to handle some Fourier analysis problems classically needing the full character table and yet tractable enough to ...
...For Un(Fq), Andr´e [1, 2, 4], Yan [
17
] and AriasCastro et al [8] found that certain unions of conjugacy classes and corresponding sums of irreducible characters give a tractable, useful theory...

...Later, in his PhD thesis [
25
], N. Yan showed how the “basic characters” can be obtained using more elementary methods which avoid Kazhan’s construction and the algebraic geometry involved in it. Yan’s approach is valid for an arbitrary prime, and was generalized later by P. Diaconis and M. Isaacs in...
...(The subsets KD,' ⊆ Um(q) are exactly the superclasses of Um(q) as explained in [15, Appendix A]; see also the papers [4, 11], or the PhD thes
is
[25].)...
...(The proofs in that paper use the assumption p ≥ m, but can be easily adapted for an arbitrary prime (see the thesis [
25
] by N. Yan); in fact, every irreducible constituent of any of the given decompositions is a supercharacter of Um(q), and thus is a Kirillov function (see [15, Theorem 5.10], or [6, Theorem 3].)...
