In a series of four papers we prove the following relaxation of the Loebl-Komlos-Sos Conjecture: For everythere exists a numbersuch that for everyevery-vertex graphwith at leastvertices of degree at leastcontains each treeof orderas a subgraph. The method to prove our result follows a strategy similar to approaches that employ the Szemer\'edi regularity lemma: we decompose the graph, find a suitable combinatorial structure inside the decomposition, and then embed the treeintousing this structure. Since for sparse graphs, the decomposition given by the regularity lemma is not helpful, we use a more general decomposition technique. We show that each graph can be decomposed into vertices of huge degree, regular pairs (in the sense of the regularity lemma), and two other objects each exhibiting certain expansion properties. In this paper, we introduce this novel decomposition technique. In the three follow-up papers, we find a combinatorial structure suitable inside the decomposition, which we then use for embedding the tree.
