Substitution Markov chains and Martin boundaries. (English) Zbl 1406.60112

Summary: Substitution Markov chains have been introduced [the first author, Substitution Markov chains with applications to molecular evolution. State College, PA: Pennsylvania State University (PhD Thesis) (2012)] as a new model to describe molecular evolution. In this note, we study the associated Martin boundaries from a probabilistic and topological viewpoint. An example is given that, although having a boundary homeomorphic to the well-known coin tossing process, has a metric description that differs significantly.
