Sturmian Sequences and Invertible Substitutions
Sturmian Sequences and Invertible Substitutions
Combinatorics It is known that a Sturmian sequence S can be defined as a coding of the orbit of rho (called the intercept of S) under a rotation of irrational angle alpha (called the slope). On the other hand, a fixed point of an invertible substitution is Sturmian. Naturally, there …
