Streszczenie
A set $A\subseteq\mathbb N$ is called complete if every sufficiently large integer can be written as a sum of distinct elements of $A$. We present a new method for proving the completeness of a set, improving results of Cassels (1960), Zannier (1992), Burr, Erdős, Graham, and Li (1996), and Hegyvári (2000). We also introduce the somewhat philosophically related notion of a dispersing set, and refine a theorem of Furstenberg (1967).
