On the Erdos-Pósa property for immersions and topological minors in tournaments

We consider the Erdos-Pósa property for immersions and topological minors in tournaments. We prove that for every simple digraph H, k ∈ N, and tournament T, the following statements hold: • If in T one cannot find k arc-disjoint immersion copies of H, then there exists a set of OH(k3) arcs that int...
