On two-point configurations in random set

Hoi Nguyen

We show that with high probability a random set of size $Θ (n^{1 - 1/ k})$ of ${1, ..., n}$ contains two elements $a$ and $a + d^{k}$ , where $d$ is a positive integer. As a consequence, we…

Squares in sumsets

Hoi Nguyen, Van Vu

A finite set $A$ of integers is square-sum-free if there is no subset of $A$ sums up to a square. In 1986, Erd\H os posed the problem of determining the largest cardinality of a sq…

Classification theorems for sumsets modulo a prime

Hoi Nguyen, Van Vu

Let $Z / pZ$ be the finite field of prime order $p$ and $A$ be a subsequence of $Z / pZ$ . We prove several classification results about the following questions: (1) When can one repr…

Subset sums in $\BZ_p$

H. H. Nguyen, E. Szemeredi, V. H. Vu

Let $\BZ_p$ be the finite field of prime order $p$ and $A$ be a subset of $\BZ_p$. We prove several sharp results about the following two basic questions: (1) When can one represen…
