Abstract
Let α > 1 be an algebraic number and ξ > 0. Denote the fractional parts of ξαn by {ξαn}. In this paper, we estimate a lower bound for the number λN (α, ξ) of integers n with 0 ≤ n < N and

Our results show, for example, the following: Let α be an algebraic integer with Mahler measure M(α) and ξ > 0 an algebraic number with ξ ∉ ℚ (α). Put [ℚ (α, ξ) : ℚ (α)] = D. Then there exists an absolute constant c satisfying

for all large N.
