Abstract:For a given graph H, a graph G is H-linked if, for every injection ϕ : V (H) → V (G), the graph G contains a subdivision of H with ϕ(v) corresponding to v, for each v ∈ V (H). Let f (H) be the minimum integer k such that every k-connected graph is H-linked. Among graphs H with at least four vertices, the exact value f (H) is only know when H is a path with four vertices or a cycle with four vertices. A kite is graph obtained from K4 by deleting two adjacent edges, i.e., a triangle together with a pendant edge.… Show more
