## Three distance theorems and combinatorics on words.(English)Zbl 0997.11051

This paper is first a very nice survey on the three distance theorem [see V. Turán-Sos, Ann. Univ. Sci. Budapest. Rolando Eötvös, Sect. Math. 1, 127-134 (1958; Zbl 0094.02903) and S. Świerczkowski, Fundam. Math. 46, 187-189 (1959; Zbl 0085.27203)] and its generalizations, going from codings of rotations to block complexities of sequences over finite alphabets, and from Beatty sequences to Sturmian sequences. It also contains new results on the frequencies of factors for sequences defined as codings of irrational rotations on $$\mathbb{R}/\mathbb{Z}$$. A large bibliography of 58 items is given.
