Beurling generalized integers with the Delone Property
-
Jeffrey C. Lagarias
Abstract
A set of Beurling generalized integers consists of the unit n0 = 1 plus the set n1 ≤ n2 ≤ … of all power products of a set of generalized primes 1 < g1 ≤ g2 ≤ g3 ≤ … with gi → ∞, with these power products arranged in increasing order and counted with multiplicity. We say that
has the Delone property if there are positive constants r, R such that R ≥ ni + 1 – ni ≥ r for all i ≥ 1. Any set
with the Delone property has unique factorization into irreducible elements and is therefore a subsemigroup of ℝ+. We classify all such semigroups which are contained in the integers
. The set of generalized primes of any such
consists of all but finitely many primes, plus finitely many other composites.
