Abstract

We extend a result of Han\v{c}l, Kolouch and Nair on the irrationality and transcendence of continued fractions. We show that for a sequence {αn}\{\alpha_n\} of algebraic integers of bounded degree, each attaining the maximum absolute value among their conjugates and satisfying certain growth conditions, the condition lim supnαn1Ddn1i=1n2(Ddi+1)= \limsup_{n \rightarrow \infty} \vert\alpha_n\vert^{\frac{1}{Dd^{n-1} \prod_{i=1}^{n-2}(Dd^i + 1)}} = \infty implies that the continued fraction α=[0;α1,α2,]\alpha = [0;\alpha_1, \alpha_2, \dots] is not an algebraic number of degree less than or equal to DD.
