An ore-type analogue of the sauer-spencer theorem

Research output: Contribution to journalArticlepeer-review


Two graphs G 1 and G 2 of order n pack if there exist injective mappings of their vertex sets into [n], such that the images of the edge sets do not intersect. Sauer and Spencer proved that if Δ (G 1) Δ (G 2) < 0.5n, then G 1 and G 2 pack. In this note, we study an Ore-type analogue of the Sauer-Spencer Theorem. Let θ(G) = max{d(u) + d(v): uv E(G)}. We show that if θ(G 1)Δ(G 2) < n, then G 1 and G 2 pack. We also characterize the pairs (G 1,G 2) of n-vertex graphs satisfying θ(G 1)Δ(G 2) = n that do not pack.
