Basic characters of the unitriangular group (for arbitrary primes)

C André - Proceedings of the American Mathematical Society, 2002 - ams.org
Let $ U_ {n}(q) $ denote the (upper) unitriangular group of degree $ n $ over the finite field
$\mathbb {F} _ {q} $ with $ q $ elements. In this paper we consider the basic (complex) …

A super-class walk on upper-triangular matrices

E Arias-Castro, P Diaconis, R Stanley - Journal of algebra, 2004 - Elsevier
Let G be the group of n× n upper-triangular matrices with elements in a finite field and ones
on the diagonal. This paper applies the character theory of Andre, Carter, and Yan to …

Ramanujan sums as supercharacters

CF Fowler, SR Garcia, G Karaali - The Ramanujan Journal, 2014 - Springer
The theory of supercharacters, recently developed by Diaconis-Isaacs and André, is used to
derive the fundamental algebraic properties of Ramanujan sums. This machinery frequently …

Supercharacter formulas for pattern groups

P Diaconis, N Thiem - Transactions of the American Mathematical Society, 2009 - ams.org
C. Andre and N. Yan introduced the idea of a supercharacter theory to give a tractable
substitute for character theory in wild groups such as the unipotent uppertriangular group …

[HTML][HTML] Supercharacters, exponential sums, and the uncertainty principle

JL Brumbaugh, M Bulkow, PS Fleming… - Journal of Number …, 2014 - Elsevier
The theory of supercharacters, which generalizes classical character theory, was recently
introduced by P. Diaconis and IM Isaacs, building upon earlier work of C. André. We study …

Branching rules in the ring of superclass functions of unipotent upper-triangular matrices

N Thiem - Journal of Algebraic combinatorics, 2010 - Springer
It is becoming increasingly clear that the supercharacter theory of the finite group of
unipotent upper-triangular matrices has a rich combinatorial structure built on set-partitions …

A supercharacter theory for the Sylow p-subgroups of the finite symplectic and orthogonal groups

CAM André, AM Neto - Journal of Algebra, 2009 - Elsevier
We define the superclasses for a classical finite unipotent group U of type Bn (q), Cn (q), or
Dn (q), and show that, together with the supercharacters defined in [CAM André, AM Neto …

Supercharacters of the Sylow p-subgroups of the finite symplectic and orthogonal groups

CAM André, AM Neto - Pacific journal of mathematics, 2008 - msp.org
We define and study supercharacters of the classical finite unipotent groups of types B n (q),
C n (q) and D n (q). We show that the results we proved in 2006 remain valid over any finite …

A supercharacter analogue for normality

E Marberg - Journal of Algebra, 2011 - Elsevier
Diaconis and Isaacs define in [8](Diaconis and Isaacs, 2008) a supercharacter theory for
algebra groups over a finite field by constructing certain unions of conjugacy classes called …
