Additive properties of dense subsets of sifted sequences Olivier Ramaré, Imre Z. Ruzsa (2001) Journal de théorie des nombres de Bordeaux We examine additive properties of dense subsets of sifted sequences, and in particular prove under very general assumptions that such a sequence is an additive asymptotic basis whose order is very well controlled.
