Abstract

We investigate the existence of subsets A and B of \({\mathbb {N}}:=\{0,1,2,\dots \}\), such that the sumset \(A+B:=\{a+b:a\in A,b\in B\}\) has prescribed asymptotic density. We solve the particular case in which B is a given finite subset of \({\mathbb {N}}\) and also the case when \(B=A\); in the later case, we generalize our result to \(kA:=\{x_1+\cdots +x_k: x_i\in A, i=1,\dots ,k\}\) for an integer \(k\ge 2.\)

The authors are thankful to Salvatore Tringali for having suggested the idea used in the proof of Case A of Theorem 2.3; to Władysław Narkiewicz, Joël Rivat, Andrzej Schinzel and Bodo Volkmann for fruitful discussions; to the anonymous referee for suggestions and remarks, that led us to render the text of the previous version richer and more precise. The late Professor Hédi Daboussi was present and made useful observations on this work in the seminar “Rencontres de théorie analytique et élémentaire des nombres” (Paris, December 2018).
