摘要：
Suppose that F(x) is an element of Z[[x]] is a Mahler function and that 1/b is in the radius of convergence of F(x) for an integer b >= 2. In this paper, we consider the approximation of F(1/b) by algebraic numbers. In particular, we prove that F(1/b) cannot be a Liouville number. If, in addition, F(x) is regular, we show that F(1/b) is either rational or transcendental, and in the latter case that F(1/b) is an S-number or a T-number in Mahler's classification of real numbers.
