Transcendence of numbers with an expansion in a subclass of complexity 2n + 1
Department of Mathematics and Turku Centre for Computer Science, University of Turku, 20014 Turku, Finland;
We divide infinite sequences of subword complexity 2n+1 into four subclasses with respect to left and right special elements and examine the structure of the subclasses with the help of Rauzy graphs. Let k ≥ 2 be an integer. If the expansion in base k of a number is an Arnoux-Rauzy word, then it belongs to Subclass I and the number is known to be transcendental. We prove the transcendence of numbers with expansions in the subclasses II and III.
Mathematics Subject Classification: 11J81 / 68R15
Key words: Transcendental numbers / subword complexity / Rauzy graph.
