Abstract

We give general results which provide asymptotic irrationality measures and estimations for the denominators of the convergents for certain almost periodic simple continued fraction expansions. As an application we obtain new irrationality measures, for example, to Napier's constant e, certain powers of e, tanh1 and a ratio of modified Bessel functions.
