A supercharacter approach to Heilbronn sums

SR Garcia, B Lutz - Journal of Number Theory, 2018 - Elsevier
Various algebraic properties of Heilbronn's exponential sum can be deduced through the
use of supercharacter theory, a novel extension of classical character theory due to Diaconis …

Equidistribution of exponential sums indexed by a subgroup of fixed cardinality

T Untrau - … Proceedings of the Cambridge Philosophical Society, 2024 - cambridge.org
We consider families of exponential sums indexed by a subgroup of invertible classes
modulo some prime power q. For fixed d, we restrict to moduli q so that there is a unique …

Moments of Gaussian Periods and Modified Fermat Curves

SR Garcia, B Lorenz, G Todd - arXiv preprint arXiv:2112.13886, 2021 - arxiv.org
We use supercharacter theory to study moments of Gaussian periods. For $ p-1= dk $ and
fixed $ k $, we compute the fourth absolute moments for all but finitely many primes $ p …

Graphical cyclic supercharacters for composite moduli

B Lutz - Proceedings of the American Mathematical Society, 2019 - ams.org
Recent work has introduced the study of graphical properties of cyclic supercharacters,
functions $\mathbb {Z}/n\mathbb {Z}\to\mathbb {C} $ whose values are exponential sums …

[PDF][PDF] Reps for JIMWLK: Applications of representation theory to a novel approach to the JIMWLK equation

J Rayner - 2018 - open.uct.ac.za
In recent work, R. Moerman and H. Weigert have introduced a truncation scheme for the
Balitsky hierarchy, arguing that this is the most general possible method for obtaining finite …

[PDF][PDF] Equidistribution of exponential sums

T Untrau - perso.eleves.ens-rennes.fr
Exponential sums are sums of roots of unity which can be defined in a very elementary way.
As sums of complex numbers of absolute value 1, they can always be trivially bounded by …

Lateral movement in undergraduate research: case studies in number theory

SR Garcia - A Project-Based Guide to Undergraduate Research in …, 2020 - Springer
We explore the thought processes, strategies, and pitfalls involved in entering new territory,
developing novel projects, and seeing them through to publication. We propose twenty-one …
