The hyperbolic circle problem over Heegner points

Dimitrios Chatzakos, Giacomo Cherubini, Stephen Lester +1

For the full modular group, we obtain a logarithmic improvement on Selberg's long-standing bound for the error term of the counting function in the hyperbolic circle problem over H…

Local average in the Hyperbolic sphere problem

Giacomo Cherubini, Christos Katsivelos

We consider a local average in the hyperbolic lattice point counting problem for the Picard group $Γ$ acting on the three-dimensional hyperbolic space. Compared to the pointwise ca…

There are Salem numbers with trace $- 3$ and every degree at least $34$

Giacomo Cherubini, Pavlo Yatsyna

We prove that there exist Salem numbers with trace $- 3$ and every even degree $\geq 34$ . Our proof combines a theoretical approach, which allows us to treat all sufficiently large…

Parity of 4-regular and 8-regular partition functions

Giacomo Cherubini, Pietro Mercuri

We give a complete characterization of the parity of $b_{8} (n)$ , the number of $8$ -regular partitions of $n$ . Namely, we prove that $b_{8} (n)$ is odd or even depending on whether or no…

Hyperbolic angles from Heegner points

Giacomo Cherubini, Alessandro Fazzari

We study lattice points on hyperbolic circles centred at Heegner points of class number one. Our main result is that, on a density one subset of radii tending to infinity, the angl…

Potential energy of totally positive algebraic integers

Giacomo Cherubini, Pavlo Yatsyna

Given positive real numbers, we prove two inequalities involving their potential energy and their power sums. We also prove an inequality involving the energy and the discriminant…

Consecutive real quadratic fields with large class numbers

Giacomo Cherubini, Alessandro Fazzari, Andrew Granville +2

For a given positive integer $k$ , we prove that there are at least $x^{1/2 - o (1)}$ integers $d \leq x$ such that the real quadratic fields $\mathbb Q(\sqrt{d+1}),\dots,\mathbb Q(\sqr…

Cyclic polytope of the simplest cubic fields

Giacomo Cherubini, Pavlo Yatsyna

In this paper, we study dilation of cyclic polytopes with the vertices defined by a generator of the simplest cubic fields. In particular, for a specific range of values, we give a…

On the variance of the nodal volume of arithmetic random waves

Giacomo Cherubini, Niko Laaksonen

Rudnick and Wigman (Ann. Henri Poincaré, 2008; arXiv:math-ph/0702081) conjectured that the variance of the volume of the nodal set of arithmetic random waves on the $d$ -dimensional…

Bykovskii-type theorem for the Picard manifold

Antal Balog, András Biró, Giacomo Cherubini +1

We generalise a result of Bykovskii to the Gaussian integers and prove an asymptotic formula for the prime geodesic theorem in short intervals on the Picard manifold. Previous work…

On Kuznetsov-Bykovskii's formula of counting prime geodesics

Giacomo Cherubini, Han Wu, Gergely Zábrádi

We generalize a formula on the counting of prime geodesics, due to Kuznetsov-Bykovskii, used in the work of Soundararajan-Young on the prime geodesic theorem. The method works over…

Second Moment of the Prime Geodesic Theorem for $PSL (2, Z [i])$

Dimitrios Chatzakos, Giacomo Cherubini, Niko Laaksonen

The remainder $E_{Γ} (X)$ in the Prime Geodesic Theorem for the Picard group $Γ = PSL (2, Z [i])$ is known to be bounded by $O (X^{3/2 + ε})$ under the assumption of the Li…

A spectral universality theorem for Maass $L$ -functions

Giacomo Cherubini, Alberto Perelli

We show that for a positive proportion of Laplace eigenvalues $λ_{j}$ the associated Hecke-Maass $L$ -functions $L (s, u_{j})$ approximate with arbitrary precision any target function $f(…

Prime Geodesic Theorem in the 3-dimensional Hyperbolic Space

Olga Balkanova, Dimitrios Chatzakos, Giacomo Cherubini +2

For $Γ$ a cofinite Kleinian group acting on $H^{3}$ , we study the Prime Geodesic Theorem on $M = Γ\ H^{3}$ , which asks about the asymptotic behaviour of length…

Mean square in the prime geodesic theorem

Giacomo Cherubini, João Guerreiro

We prove upper bounds for the mean square of the remainder in the prime geodesic theorem, for every cofinite Fuchsian group, which improve on average on the best known pointwise bo…

Almost periodic functions and hyperbolic counting

Giacomo Cherubini

In this paper we prove the existence of asymptotic moments, and an estimate on the tails of the limiting distribution, for a specific class of almost periodic functions. Then we in…

On the variance of the error term in the hyperbolic circle problem

Giacomo Cherubini, Morten S. Risager

Let $e (s)$ be the error term of the hyperbolic circle problem, and denote by $e_{α} (s)$ the fractional integral to order $α$ of $e (s)$ . We prove that for any small $α > 0$ the asymptot…
