Small values of signed harmonic sums

Sandro Bettin, Giuseppe Molteni, Carlo Sanna

For every $τ \in R$ and every integer $N$ , let $m_{N} (τ)$ be the minimum of the distance of $τ$ from the sums $\sum_{n = 1}^{N} s_{n} / n$ , where $s_1, \ldots, s_n \in \{-1…

Greedy approximations by signed harmonic sums and the Thue--Morse sequence

Sandro Bettin, Giuseppe Molteni, Carlo Sanna

Given a real number $τ$ , we study the approximation of $τ$ by signed harmonic sums $σ_{N} (τ) := \sum_{n \leq N} s_{n} (τ) / n$ , where the sequence of signs $(s_{N} (τ))_{N \in N}$ i…
