摘要
A famous conjecture of Erdos and Sos states that every graph with average degree more than k - 1 contains all trees with k edges as subgraphs. We prove that the Erdos-Sos conjecture holds approximately, if the size of the embedded tree is linear in the size of the graph, and the maximum degree of the tree is sublinear.
