Through connecting dynamical structures and quantity conception this graduate textbook on ergodic thought covers a hugely lively region of arithmetic, the place a number of strands of study open up. After introducing number-theoretical dynamical structures, the textual content touches on foundations and renewal idea ahead of protecting countless ergodic idea. purposes similar to endured fraction growth and sum-level units are mentioned in addition.

Proof. Fix n ≥ 2 and let x = [n, x2 , x3 , . ], so x ∈ (1/(n + 1), 1/n]. Then, we have that F * (x) = F n ([n, x2 , x3 , . ]) = F n−1 ([n − 1, x2 , x3 , . ]) = · · · = F([1, x2 , x3 , . ]) = [x2 , x3 , . ] = G(x). On the other hand, if x = [1, x2 , x3 , . ] ∈ (1/2, 1], then ρ(x) is equal to zero and so we have that F * (x) = F(x), which is again equal to G(x), since G|(1/2,1] = F |(1/2,1] . Our next aim is to describe a coding generated by the Farey map. The two open sets {B0 := (0, 1/2), B1 := (1/2, 1)} form a Markov partition for F.

X n ) coincides with the set F x1 ◦ F x2 ◦ · · · ◦ F x n ((0, 1)). We will refer to these successive reﬁnements as the Farey decomposition. There is another way to describe these cylinder sets, in terms of the classical construction of Stern–Brocot intervals (cf. [Ste58], [Bro61]). For each n ≥ 0, the elements of the n-th member of the Stern–Brocot sequence Bn := s n,k : k = 1, . . , 2n + 1 t n,k are deﬁned recursively as follows: – s0,1 := 0 and s0,2 := t0,1 := t0,2 := 1; – s n+1,2k−1 := s n,k and t n+1,2k−1 := t n,k , for k = 1, .

Then ω ∧ γ = ε. Of course, if two (ﬁnite or inﬁnite) words ω and τ are equal, then ω ∧ τ = ω = τ. Let us now introduce a metric on the space EN which reﬂects the idea that two words are close if they share a long initial block. In other words, the longer their common initial subword, the closer two words are. 10). 10. Let the metric d : EN × EN → [0, 1] be deﬁned by d(ω, τ) := 2−|ω∧τ| . If ω and τ have no common initial block, then ω ∧ τ = ε. Thus, |ω ∧ τ| = 0 and d(ω, τ) = 1. On the other hand, if the two inﬁnite words ω and τ are such that ω = τ, then |ω ∧ τ| = ∞ and we deﬁne (1/2)+∞ := 0.
