%0 Journal Article %T Automatic sets of rational numbers %A Eric Rowland %A Jeffrey Shallit %J Computer Science %D 2011 %I arXiv %R 10.1142/S0129054115500197 %X The notion of a k-automatic set of integers is well-studied. We develop a new notion - the k-automatic set of rational numbers - and prove basic properties of these sets, including closure properties and decidability. %U http://arxiv.org/abs/1110.2382v4
