Given graphs G and H, we define an H-tiling in G to be a collection of vertex-disjoint copies of H in G. Let η > 0. We call an H-tiling perfect if it covers all of the vertices in G and η-almost perfect if it covers all but at most an η-proportion of the vertices in G. An important theorem of Komlós provides the minimum degree of G which ensures an η-almost perfect H-tiling in G. We present a degree sequence strengthening of this result and provide a proof sketch. This is joint work with Hong Liu and Andrew Treglown.

Using the aforementioned theorem of Komlós, Kühn and Osthus determined the minimum degree of G that ensures a perfect H-tiling in G. We present a degree sequence version of their result as an application of our degree sequence Komlós theorem. This is joint work with Andrew Treglown.
