Density of integral sets with missing differences
Abstract
Motzkin posed the problem of finding the maximal density $μ(M)$ of sets of integers in which the differences given by a set $M$ do not occur. The problem is already settled when $|M|\leq 2$ and $M$ is a finite arithmetic progression. In this paper, we determine $μ(M)$ when $M$ has some other structure. For example, we determine $μ(M)$ when $M$ is a finite geometric progression.
