Distributions of left prime truncations

Vivian Kuperberg, Matilde Lalín

The prime number 357686312646216567629137 is notable because of the unusual property that it remains prime successively on removing the left digit until there are no remaining digi…

Murmurations in the depth aspect

Claire Burrin, Vivian Kuperberg, Min Lee +2

We compute the murmuration density function for the family of Hecke forms of weight $k$ and prime power level $N = ℓ^{a}$ , with $ℓ$ a fixed odd prime and $a \to \infty$ .

Arithmetic constants for symplectic variances of the divisor function

Vivian Kuperberg, Matilde Lalín

In [arXiv:2212.04969], the authors stated some conjectures on the variance of certain sums of the divisor function $d_{k} (n)$ over number fields, which were inspired by analogous res…

Positive density for consecutive runs of sums of two squares

Noam Kimmel, Vivian Kuperberg

We study the distribution of consecutive sums of two squares in arithmetic progressions. We show that for any odd squarefree modulus $q$ , any two reduced congruence classes $a_{1}$ a…

The gaps in the multiplication table

Emmanuel Kowalski, Vivian Kuperberg

We determine the complete list of the gaps between successive elements of the multiplication table of the first N integers.

Statistics of ranks, determinants and characteristic polynomials of rational matrices

Muhammad Afifurrahman, Vivian Kuperberg, Alina Ostafe +1

We consider the set of $n \times n$ matrices with rational entries having numerator and denominator of size at most $H$ and obtain upper and lower bounds on the number of such matri…

Odd moments and adding fractions

Thomas F. Bloom, Vivian Kuperberg

We prove near-optimal upper bounds for the odd moments of the distribution of coprime residues in short intervals, confirming a conjecture of Montgomery and Vaughan. As an applicat…

Lower bounds on weighted moments of primes in short intervals in number fields

Régis de la Bretèche, Vivian Kuperberg

We consider an analog of a conjecture of Montgomery and Soundararajan on the moments of primes in short intervals in number fields; this analog was discussed and heuristically deri…

Consecutive runs of sums of two squares

Noam Kimmel, Vivian Kuperberg

We study the distribution of consecutive sums of two squares in arithmetic progressions. If ${E_{n}}_{n \in N}$ is the sequence of sums of two squares in increasing order,…

Sums of singular series along arithmetic progressions and with smooth weights

Vivian Kuperberg

Sums of the singular series constants that appear in the Hardy--Littlewood $k$ -tuples conjectures have long been studied in connection to the distribution of primes. We study const…

Symplectic conjectures for sums of divisor functions and explorations of an orthogonal regime

Vivian Kuperberg, Matilde Lalín

In [arXiv:2107.01437], the authors studied the mean-square of certain sums of the divisor function $d_{k} (f)$ over the function field $F_{q} [T]$ in the limit as $q \to \infty$ …

Sums of singular series with large sets and the tail of the distribution of primes

Vivian Kuperberg

In 1976, Gallagher showed that the Hardy--Littlewood conjectures on prime $k$ -tuples imply that the distribution of primes in log-size intervals is Poissonian. He did so by computi…

Odd moments in the distribution of primes

Vivian Kuperberg

Montgomery and Soundararajan showed that the distribution of $ψ (x + H) - ψ (x)$ , for $0 \leq x \leq N$ , is approximately normal with mean $\sim H$ and variance $\sim H lo g (N / H)$ , whe…

Sums of divisor functions and von Mangoldt convolutions in $F_{q} [T]$ leading to symplectic distributions

Vivian Kuperberg, Matilde Lalín

In [arXiv:1504.07804], Keating, Rodgers, Roditty-Gershon and Rudnick established relationships of the mean-square of sums of the divisor function $d_{k} (f)$ over short intervals and…

On pseudo-polynomials divisible only by a sparse set of primes and $\a$-primary pseudo-polynomials

Vivian Kuperberg

We explore two questions about pseudo-polynomials, which are functions $f : N \to Z$ such that $k$ divides $f (n + k) - f (n)$ for all $n, k$ . First, for certain arbitrari…

Sums of singular series and primes in short intervals in algebraic number fields

Vivian Kuperberg, Brad Rodgers, Edva Roditty-Gershon

Gross and Smith have put forward generalizations of Hardy - Littlewood twin prime conjectures for algebraic number fields. We estimate the behavior of sums of a singular series tha…
