Homotopy types of Hom complexes of graph homomorphisms whose codomains are square-free

Soichiro Fujii, Kei Kimura, Yuta Nozaki

Given finite simple graphs $G$ and $H$ , the Hom complex $Hom (G, H)$ is a polyhedral complex having the graph homomorphisms $G \to H$ as the vertices. We determine the homoto…

Homotopy types of Hom complexes of graph homomorphisms whose codomains are cycles

Soichiro Fujii, Yuni Iwamasa, Kei Kimura +2

For simple graphs $G$ and $H$ , the Hom complex $Hom (G, H)$ is a polyhedral complex whose vertices are the graph homomorphisms $G \to H$ and whose edges connect the pairs of…
