Let α be an irrational number between 0 and 1 with continued fraction expansion 0 ; a 1 + 1 , a 2 , a 3 , ź , where a n ź 1 ( n ź 1 ). Define a sequence of numbers { q n } n ź - 1 by q - 1 = 1 , q 0 = 1 , q n = a n q n - 1 + q n - 2 ( n ź 1 ).

We prove that all suffixes of a two-way infinite extension of an irrational characteristic word can be represented as Markov word patterns (MWPs) of type 1 and under some conditions, as MWPs of type 2. For each of these MWPs, the pairs of seed words

The Bernoulli word B ( ξ ) of an irrational number ξ is an infinite word over the alphabet { a , b } , in which the n th letter is a if [ ( n + 1 ) ξ + 1 2 ] − [ n ξ + 1 2 ] = 0 and is b if [ ( n + 1 ) ξ + 1 2 ] − [ n ξ + 1 2 ] = 1 ( n ≥

For each suffix X of a two-way infinite Fibonacci word, we consider the factorization X = u k u k + 1 u k + 2 ? , where k is a positive integer, and the length of the factor u i is the i th Fibonacci number ( i ? k ) . It is called the Fibonacci fact

Let τ = (√5 - 1)/2. Let a, b be two distinct letters. The infinite Fibonacci word is the infinite word G = babbababbabbababbababbabba... whose nth letter is a (resp., b) if [(n + 1)τ] - [nτ] = 0 (resp., 1). For a factor w of G, the location of w

Let β be an irrational number between 0 and 1. The characteristic word f(β) of β is defined to be the infinite word over {0, 1} whose nth letter is [(n + 1)β] -[nβ], n ≥ 1. It is well known that, for each m ≥ 1, f(β) has exactly m + 1 disti

For each nonempty binary word w = c1c2...Cq, where ci ∈ {0, 1}, the nonnegative integer Σi=1q (q + 1 - i)ci is called the moment of w and is denoted by M(w). Let [w] denote the conjugacy class of w. Define M([w]) = {M(u): u ∈ [w]}, N(w) = {M(u)
