Therefore a.s. a vertex of degree ... more work. We will present this proof in the final section of the paper. The crux of the proof of Theorem 1.2 lies in showing that  k is a threshold for G k n,M in the sense o...

... is ultimately periodic. Proof. It is a direct consequence of Theorem 3.10. Corollary 3.13. None of the Arnoux-Rauzy sequences (A-strict episturmian sequences) are balanced. Proof. It follows from the ... equivalent. There are two different generalizations of Sturmian sequences for alphabets of cardinality k ≥ 3. A natural generalization of Sturmian sequences is the set of infinite e...

Fix a choice of functions f, g : N → R ≥0 such ... still a connector of T , contradicting the minimality of S ∗ . Hence x is a neighbor of v 0 . By symmetric reasoning, y is also a neighbor of v 0 . We have argued that the endpoint...
