A Lower Bound for the Size of a Sum of Dilates

Zeljka Ljujic

Let $A$ be a subset of integers and let $2 \cdot A + k \cdot A = {2 a_{1} + k a_{2} : a_{1}, a_{2} \in A}$ . Y. O. Hamidoune and J. Ru\' e proved that if $k$ is an odd prime and $A$ a finite set of i…

Periodicity of complementing multisets

Zeljka Ljujic

Let $A$ be a finite multiset of integers. If $B$ be a multiset such that $A$ and $B$ are $t$ -complementing multisets of integers, then $B$ is periodic. We obtain the Biro-type uppe…
