Description (last modified by )
An adic language is a symbolic counterpart to the renormalization in dynamics and generalize what are called "substitution fixed point" (roughly implemented in sage/combinat/words/). Such kind of languages are described by an infinite sequence of substitutions and many algorithms exist
- enumeration of words of length n
- enumeration of left/right special factors
- synchronization delays
- ...
Particular cases should be consider apart:
- Sturmian languages
- Interval Exchange Transformations
- Free Group Automorphisms
- ...
