“…It may denote real numbers whose continued fraction expansion has some regularity, or can be produced by a simple algorithm (by a simple Turing machine, for example), or arises from a simple dynamical system... The main results of the present work are two new combinatorial transcendence criteria, which considerably improve upon those from [5,13,8]. It is of a particular interest that such criteria naturally yield, in a unified way, several new results on the different approaches of the above mentioned notion of simplicity/complexity for the continued fraction expansions of algebraic real numbers of degree at least three.…”
