Minimal obstructions to $C_5$-coloring in hereditary graph classes

Jan Goedgebeur, Jorik Jooken, Karolina Okrasa +2

For graphs $G$ and $H$, an $H$-coloring of $G$ is an edge-preserving mapping from $V(G)$ to $V(H)$. Note that if $H$ is the triangle, then $H$-colorings are equivalent to $3$-color…
