A local approach to the Erdős-Sós conjecture
arXiv:1804.06791
Abstract
A famous conjecture of Erdős and Sós states that every graph with average degree more than contains all trees with 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.
