Given a set B ⊂ N, we investigate the existence of a set A ⊂ N such that the sumset A + B = {a + b : a ∈ A, b ∈ B} has a prescribed asymptotic density. A set B = {b1, b2, . . .} is said to be highly sparse if B is either finite or infinite with limj→∞ bj+1/bj = ∞. In this note, we prove that if B is highly sparse, such a set A exists. This generalizes a recent result by Faisant et al.

Additive Complements for a Given Asymptotic Density
We investigate the existence of subsets A and B of $${\mathbb {N}}:=\{0,1,2,\dots \}$$ N : = { 0 , 1 , 2 , ⋯ } , such that the sumset $$A+B:=\{a+b:a\in A,b\in B\}$$ A + B : = { a + b : a ∈ A , b ∈ BExpand
Exact additive complements
Let $A,B$ be sets of positive integers such that $A+B$ contains all but finitely many positive integers. Sarkozy and Szemeredi proved that if $ A(x)B(x)/x \to 1$, then $A(x)B(x)-x \to \infty $. ChenExpand

Let $\mathrm{d}(A)$ be the asymptotic density (if it exists) of a sequence of integers $A$. For any real numbers $0\leq\alpha\leq\beta\leq 1$, we solve the question of the existence of a sequence $A$Expand

In this paper some links between the density of a set of integers and the density of its sumset, product set and set of subset sums are presented.
