### Configuration spaces, graded spaces, and polysymmetric functions

• Mathematics
• 2022
This paper presents techniques for computing motivic measures of configuration spaces when points of the base space are weighted. This generality allows for a more flexible notion of configuration

### On unit signatures and narrow class groups of odd abelian number fields: Galois structure and heuristics

• Mathematics
• 2021
This paper is an extension of the work of Dummit and Voight on modeling the 2-Selmer group of number fields. We extend their model to Sn-number fields of even degree and develop heuristics on the

### SATO–TATE EQUIDISTRIBUTION OF CERTAIN FAMILIES OF ARTIN $L$ -FUNCTIONS

• Mathematics
Forum of Mathematics, Sigma
• 2019
We study various families of Artin $L$ -functions attached to geometric parametrizations of number fields. In each case we find the Sato–Tate measure of the family and determine the symmetry type of

### The asymptotic growth of torsion homology for arithmetic groups

• Mathematics
Journal of the Institute of Mathematics of Jussieu
• 2012
Abstract When does the amount of torsion in the homology of an arithmetic group grow exponentially with the covolume? We give many examples where this is the case, and conjecture precise conditions.

### On the asymptotics of cubic fields ordered by general invariants

• Mathematics
• 2022
In this article, we introduce a class of invariants of cubic ﬁelds termed “generalized discriminants”. We then obtain asymptotics for the families of cubic ﬁelds ordered by these invariants. In

### Low degree Hurwitz stacks in the Grothendieck ring

• Mathematics
• 2022
For $2 \leq d \leq 5$, we show that the class of the Hurwitz space of smooth degree $d$, genus $g$ covers of $\mathbb P^1$ stabilizes in the Grothendieck ring of stacks as $g \to \infty$. We will

### Heuristics for the asymptotics of the number of $S_n$-number fields

• Mathematics
• 2020
We give a heuristic argument supporting conjectures of Bhargava on the asymptotics of the number of $S_n$-number fields having bounded discriminant. We then make our arguments rigorous in the case

### DENSITY RESULTS FOR SPECIALIZATION SETS OF GALOIS COVERS

• Mathematics
Journal of the Institute of Mathematics of Jussieu
• 2019
Abstract We provide evidence for this conclusion: given a finite Galois cover $f:X\rightarrow \mathbb{P}_{\mathbb{Q}}^{1}$ of group $G$ , almost all (in a density sense) realizations of $G$ over

### The number of quartic $D_4$-fields ordered by conductor

• Mathematics
• 2017
We consider families of number fields of degree 4 whose normal closures over $\mathbb{Q}$ have Galois group isomorphic to $D_4$, the symmetries of a square. To any such field $L$, one can associate
