The Combinatorics of Solving Linear Equations
Ronald Graham (University of California, San Diego)

Abstract

One of the fundamental topics in combinatorics involves deciding whether some given linear equation has solutions with all its variables lying in some restricted set, and if so, estimating how many such solutions there are. In this talk, we will describe some of the old and new results in this area, as well as discuss a number of unsolved problems.
