Circle coverings driven by arithmetic sequences: a percolation approach to Diophantine approximation and fractal intersections

Manuel Hauke, Andrei Shubin, Eduard Stefanescu +1

We study problems on covering $[0, 1)$ by shrinking intervals centered at the points ${q_{n} x}$ , where $(q_{n})_{n \in N}$ is a given real-valued sequence and $x \in [0, 1)$ i…

On the maximal volume of empty convex bodies amidst multivariate dilates of a lacunary integer sequence

Eduard Stefanescu

Let $(a_n)_{n \in \mathbb{N}}$ be a lacunary sequence of integers satisfying the Hadamard gap condition. For any fixed dimension $d \geq 1$ , we establish asymptotic upper bounds…

The dispersion of dilated lacunary sequences, with applications in multiplicative Diophantine approximation

Eduard Stefanescu

Let $(a_{n})_{n \in N}$ be a Hadamard lacunary sequence. We give upper bounds for the maximal gap of the set of dilates ${a_{n} α}_{n \leq N}$ modulo 1, in terms of $N$ . For…
