Abstract

We improve the results in [1] on the characterization of multiple points in rational based number system, in connection with Mahler’s Z-number problem. As a by-product, we show that when p > q2, there exists a positive x such that the fractional part of x(p/q)n (n = 0, 1, . . . ) stays in a Cantor set (Theorem 2.5). Hausdorff dimension of the set is positive but tends to zero as p → ∞ when q is fixed.


Keywords

Irregularity of distribution, number system, Z-number.
