Cross representations of additive complements of $r$ -th powers

Yuchen Ding, Ben Krause, Csaba Sándor +2

Let $N$ be the set of natural numbers and $S_{r} = {1^{r}, 2^{r}, 3^{r}, \dots}$ the set of $r$ -th powers, where $r \geq 2$ is a natural number. Let $\mathcal{W}_r…

Problems 66 and 67 on sums of residue classes and primes of András Sárközy's collection of unsolved problems

Yuchen Ding, Christian Elsholtz, Yu-Chen Sun

In this note, we discuss two problems of Sárközy (2001). In particular, we prove an optimal result on sumsets of sparse subset of primes.
