It is well known that no rational number is approximable to order higher than 1. Roth [3] showed that an algebraic number is not approximable to order greater than 2. On the other hand it is easy to construct numbers, the Liouville numbers, which are approximable to any order (see [2], p. 162). We are led to the question, “Let Nn(α, β) denote the number of distinct rational points with denominators ≦ n contained in an interval (α, β). What is the behaviour of Nn(α, + 1/n) as α varies on the real line?” We shall prove that and that there are “compressions” and “rarefactions” of rational points on the real line.

AbstractThe aim of this work is to adapt a construction of the so-called $U_{m}$-numbers ($m\gt 1$), which are extended Liouville numbers with respect to algebraic numbers of degree $m$ but not with respect to algebraic numbers of degree less than $m$, to the $p$-adic frame.
