Translation invariant quadratic forms in $8$ variables and dense sets of primes

Zhaochen Pei, Maoru Tan, Weiwen Zhang +1

Let $Q$ be a translation invariant indefinite quadratic form in $8$ variables. Let $P$ be the set of all primes. Let $A \subset P \cap {1, \dots, X}$ . By…

On additive complements in natural numbers

Quan-Hui Yang, Lilu Zhao

We prove that for additive complements $A$ and $B$ , if $x \to + \infty lim sup \frac{A ( x ) B ( x )}{x} < \frac{4}{3},$ then $A (x) B (x) - x \to + \infty (x \to + \infty) .$ This impro…

Products of Two Integers Avoiding Perfect Powers

Quan-Hui Yang, Lilu Zhao

For integers $d \geq 3$ , let $F_{2, d} (n)$ be the largest size of a subset of $[n]$ containing no two distinct elements whose product is a perfect $d$ -th power, and let $f_{2, d} (n)$ …

Exterior Algebra and an Extension of the Feng-Sun-Xiang Theorem in $p$ -groups

Zhi-Wei Sun, Lilu Zhao

Let $G$ be a finite group with $∣ G ∣ = p^{m}$ where $p$ is a prime and $m$ is a positive integer. Let $k < p$ . Let $a_{1}, \dots, a_{k} \in G$ be pairwise distinct and let $b_{1}, \dots, b_{k} \in G$ …
