We study the rainbow version of the graph commonness property: a graph $H$ is $r$ -rainbow common if the number of rainbow copies of $H$ (where all edges have distinct colors) in an…

Size of the largest sum-free subset of $[n]^{3}$ and $[n]^{4}$

Saba Lepsveridze, Yihang Sun

We determine the density of the largest sum-free subset of the lattice cube ${1, 2, \dots, n}^{d}$ for $d = 3$ and $d = 4$ . This solves a conjecture of Cameron and Aydinian in dime…
