Bounds on point configurations determined by distances and dot products

Combinatorics 2020-12-01 v1 Metric Geometry

Abstract

We study a family of variants of Erd\H os' unit distance problem, concerning distances and dot products between pairs of points chosen from a large finite point set. Specifically, given a large finite set of nn points EE, we look for bounds on how many subsets of kk points satisfy a set of relationships between point pairs based on distances or dot products. We survey some of the recent work in the area and present several new, more general families of bounds.
