A Local Approach to the Erdős-Sós Conjecture
Abstract
A famous conjecture of Erdős-Sós states that every graph with average degree more than k-1 contains all trees with k edges as subgraphs. We prove that the Erdős-Sós 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.
