[HTML][HTML] The divergence Borel–Cantelli lemma revisited

V Beresnevich, S Velani - Journal of mathematical analysis and …, 2023 - Elsevier
Abstract Let (Ω, A, μ) be a probability space. The classical Borel–Cantelli Lemma states that
for any sequence of μ-measurable sets E i (i= 1, 2, 3,…), if the sum of their measures …

Towards van der Waerden's conjecture

S Chow, R Dietmann - Transactions of the American Mathematical Society, 2023 - ams.org
How often is a quintic polynomial solvable by radicals? We establish that the number of such
polynomials, monic and irreducible with integer coefficients in $[-H, H] $, is $ O (H^{3.91}) …

[HTML][HTML] Dispersion and Littlewood's conjecture

S Chow, N Technau - Advances in Mathematics, 2024 - Elsevier
Let ε> 0. We construct an explicit, full-measure set of α∈[0, 1] such that if γ∈ R then, for
almost all β∈[0, 1], if δ∈ R then there are infinitely many integers n⩾ 1 for which n‖ n α …

Moment transference principles and multiplicative diophantine approximation on hypersurfaces

S Chow, H Yu - arXiv preprint arXiv:2408.10911, 2024 - arxiv.org
We determine the generic multiplicative approximation rate on a hypersurface. There are
four regimes, according to convergence or divergence and curved or flat, and we address all …

The Duffin-Schaeffer conjecture with a moving target

M Hauke, FA Ramirez - arXiv preprint arXiv:2407.05344, 2024 - arxiv.org
We prove the inhomogeneous generalization of the Duffin-Schaeffer conjecture in
dimension $ m\geq 3$. That is, given $\mathbf {y}\in\mathbb {R}^ m $ and $\psi:\mathbb …

An effective Ratner equidistribution theorem for multiplicative Diophantine approximation on planar lines

S Chow, L Yang - arXiv preprint arXiv:1902.06081, 2019 - arxiv.org
In this paper, we prove an effective asymptotic equidistribution result for one-parameter
unipotent orbits in $\mathrm {SL}(3,\mathbb {R})/\mathrm {SL}(3,\mathbb {Z}) $. This enables …

Remarks on sums of reciprocals of fractional parts

B Borda - arXiv preprint arXiv:2305.07394, 2023 - arxiv.org
The Diophantine sums $\sum_ {n= 1}^ N\| n\alpha\|^{-1} $ and $\sum_ {n= 1}^ N n^{-1}\|
n\alpha\|^{-1} $ appear in many different areas including the ergodic theory of circle …

Non-Salem sets in multiplicative Diophantine approximation

B Tan, QL Zhou - arXiv preprint arXiv:2409.12557, 2024 - arxiv.org
In this paper, we answer a question of Cai-Hambrook in (arXiv $\colon $2403.19410).
Furthermore, we compute the Fourier dimension of the multiplicative $\psi $-well …
