Abstract
Let be a set of natural numbers. A set , a set of natural numbers, is an additive complement of the set if all sufficiently large natural numbers can be represented in the form , where and . Erd\H{o}s proposed a conjecture that every infinite set of natural numbers has a sparse additive complement, and in 1954, Lorentz proved this conjecture. This article describes the existence or non-existence of those additive complements of the set that is a subset of the complement of . We provide a ratio test to verify the existence of such additive complements. In precise, we prove that if is a set of natural numbers such that for and , then there exists a set such that is a sparse additive complement of the set .
