We announce the classification of Sato-Tate groups of abelian threefolds over number fields; there are 410 possible conjugacy classes of closed subgroups of USp(6) that occur. We summarize the key points of the "upper bound" aspect of the classification, and give a more rigorous treatment of the "lower bound" by realizing 33 groups that appear in the classification as maximal cases with respect to inclusions of finite index. Further details will be provided in a subsequent paper.

Sato-Tate groups of abelian threefolds
Given an abelian variety over a number field, its Sato-Tate group is a compact Lie group which conjecturally controls the distribution of Euler factors of the L-function of the abelian variety. ItExpand
Sato-Tate Distributions of Catalan Curves
For distinct odd primes p and q, we define the Catalan curve Cp,q by the affine equation y = x − 1. In this article we construct the Sato-Tate groups of the Jacobians in order to study the limitingExpand
Determining monodromy groups of abelian varieties
Associated to an abelian variety over a number field are several interesting and related groups: the motivic Galois group, the Mumford-Tate group, $\ell$-adic monodromy groups, and the Sato-TateExpand
On a local-global principle for quadratic twists of abelian varieties
Let A and A be abelian varieties defined over a number field k of dimension g ≥ 1. For g ≤ 3, we show that the following local-global principle holds: A and A are quadratic twists of each other ifExpand
Auto-correlation functions of Sato-Tate distributions and identities of symplectic characters
The Sato-Tate distributions for genus 2 curves (conjecturally) describe the statistics of numbers of rational points on the curves. In this paper, we explicitly compute the auto-correlation functionsExpand
Towards the Sato–Tate groups of trinomial hyperelliptic curves
We consider the identity component of the Sato-Tate group of the Jacobians of curves of the form $$C_1:y^2=x^{2g+2}+c, C_2:y^2=x^{2g+1}+cx, C_3:y^2=x^{2g+1} +c,$$ where $g$ is the genus of the curveExpand
Distribution of values of Gaussian hypergeometric functions
In the 1980’s, Greene defined hypergeometric functions over finite fields using Jacobi sums. The framework of his theory establishes that these functions possess many properties that are analogous toExpand
Sato-Tate Distributions of $y^2=x^p-1$ and $y^2=x^{2p}-1$
We determine the Sato-Tate groups and prove the generalized Sato-Tate conjecture for the Jacobians of curves of the form $$ y^2=x^p-1 \text{ and } y^2=x^{2p}-1,$$ where $p$ is an odd prime. OurExpand

Computing $L$-polynomials of Picard curves from Cartier-Manin matrices
We study the sequence of zeta functions $Z(C_p,T)$ of a generic Picard curve $C:y^3=f(x)$ defined over $\mathbb{Q}$ at primes $p$ of good reduction for $C$. By determining the density of the set ofExpand


Sato-Tate groups of some weight 3 motives
We establish the group-theoretic classification of Sato-Tate groups of self-dual motives of weight 3 with rational coefficients and Hodge numbers h 3,0 = h 2,1 = h 1,2 = h 0,3 = 1. We then describeExpand

Sato–Tate distributions and Galois endomorphism modules in genus 2
Abstract For an abelian surface A over a number field k, we study the limiting distribution of the normalized Euler factors of the L-function of A. This distribution is expected to correspond toExpand
