Abstract

Many recent results in combinatorics concern the relationship between the size of a set and the number of distances determined by pairs of points in the set. One extension of this question considers configurations within the set with a specified pattern of distances. In this paper, we use graph-theoretic methods to prove that a sufficiently large set $E$ must contain at least $C_G\left|E\right|$ distinct copies of any given weighted tree $G$, where $C_G$ is a constant depending only on the graph $G$.
