An extension of the rainbow Erdős-Rothschild problem

Carlos Hoppen, Hanno Lefmann, Denilson Amaral Nolibos

Given integers $r \geq 2$ , $k \geq 3$ and $2 \leq s \leq (2 k)$ , and a graph $G$ , we consider $r$ -edge-colorings of $G$ with no copy of a complete graph $K_{k}$ on $k$ vertice…

Counting orientations of graphs with no strongly connected tournaments

Fábio Botler, Carlos Hoppen, Guilherme Oliveira Mota

Let $S_{k} (n)$ be the maximum number of orientations of an $n$ -vertex graph $G$ in which no copy of $K_{k}$ is strongly connected. For all integers $n$ , $k \geq 4$ where $n \geq 5$ or $k…
