Abstract

We revisit Yu's second moment formula for incomplete Eisenstein series and give uniform bounds for secondary terms appearing in this formula. We use these bounds to improve results on distribution of integer points on the light cone corresponding to an indefinite quadratic form, as well as intrinsic Diophantine approximation on ellipsoids, and counting holonomy vectors of saddle connections of Veech surfaces.

Arithmetic Upper and Lower Bounds for the Denumerant Function

We use an elementary arithmetic argument, going back to Blom and Fr{ö}berg, to obtain upper and lower bounds for the denumerant function of Sylvester for arbitrary positive integers $a_1,\dots,a_k$. The bounds hold along the multiples of $\gcd(a_1,\dots,a_k)$, share the leading term of the denumerant, and yield its asymptotic behaviour with an explicit error term; for large $n$ and under a mild condition, a polynomial refinement of the lower bound improves on the lower bound of Agnarsson.

The Riemann hypothesis

The Weyl symbolic calculus of operators leads to the construction, if one takes for symbol a certain distribution decomposing over the zeros of the Riemann zeta function, of an operator with the following property: the Riemann hypothesis is equivalent to the validity of a collection of estimates involving this operator. Pseudodifferential arithmetic, a novel chapter of pseudodifferential operator theory, makes it possible to make the operator under study fully explicit. This leads to a proof of the conjecture.

On the representation functions of certain numeration systems

Let $β>1$ be fixed. We consider the $(\mathbf{b},\mathcal{D})$-numeration system, where the base sequence $\mathbf{b}=(b_k)_{k\geq 0}$ consists of positive real numbers satisfying $\lim_{k\rightarrow \infty}b_{k+1}/b_k=β$, and the digit set $\mathcal{D}\ni 0$ is a finite set of nonnegative real numbers containing at least two elements. Let $r_{\mathbf{b},\mathcal{D}}(λ)$ denote the number of representations of a given $λ\in\mathbb{R}$ in the form $\sum_{k\ge 0}δ_kb_k$ with digits $δ_k\in \mathcal{D}$. We establish upper bounds for $r_{\mathbf{b},\mathcal{D}}(λ)$ as well as asymptotic formulas for its arbitrary moments. Furthermore, we prove that the associated Dirichlet series $ζ_{\mathbf{b},\mathcal{D}}(s):=\sum_{λ>0}r_{\mathbf{b},\mathcal{D}}(λ)λ^{-s}$ admits a meromorphic continuation to the entire complex plane when $b_k=β^{k}$, and to the half-plane $\mathrm{Re}(s)>\log_β\mathcal{D}-γ$ when $b_k=β^{k}+O(β^{(1-γ)k})$ for any fixed $γ\in(0,1]$. Within the regions of continuation, we determine all candidate poles, compute their corresponding residues, and locate the trivial zeros of $ζ_{\mathbf{b},\mathcal{D}}(s)$. As an application, we resolve several problems posed by Chow and Slattery concerning partitions into distinct terms of certain integer sequences.
