For a given graph $H$, a graph $G$ is H-linked if, for every injection $\varphi: V(H) \to V(G)$, the graph $G$ contains a subdivision of $H$ with $\varphi(v)$ corresponding to $v$ for each $v\in V(...

The motivating question of this paper is to ask when, given a group A and generating set X for A, one can find a Cayley map CM(A,X,@r) with representativity at least two (also called a strong embedding of the graph; note that in such an embedding, ea

We prove that if G is a 5-connected graph embedded on a surface Σ (other than the sphere) with face-width at least 5, then G contains a subdivision of K5. This is a special case of a conjecture of P. Seymour, that every 5-connected nonplanar graph c
