On large semi-linked graphs

Let H be a multigraph, possibly with loops, and consider a set S ⊆ V(H). A (simple) graph G is (H,S)-semi-linked if, for every injective map f:S→V(G), there exists an injective map g:V(H)\S→V(G)\f(S) and a set of |E(H)| internally disjoint paths in G connecting pairs of vertices of f(S) ∩ g(V(H)\S) for every edge between the corresponding vertices of H. This new concept of (H,S)-semi-linkedness is a generalization of H-linkedness. We establish a sharp minimum degree condition for a sufficiently large graph G to be (H,S)-semi-linked.
