摘要

The strip entropy is studied in this article. First, we prove that the strip entropy approximation is valid for some ray of Markov tree-shifts on Markov-Cayley trees. This result extends the previous result of [Petersen-Salama, Discrete & Continuous Dynamical Systems, 2020] on the conventional 2 tree. Second, we obtain that the rates of convergence of tree-shift associated with a primitive matrix A on the d tree are linear (with respect to the number of points in transversal direction), which is reminiscent of the result on \(\mathbb {Z}^2\) Z 2 [Pavlov, The Annals of Probability, 2012]. Lastly, we prove that the rates of convergence of strip entropy approximation are closely related to the expanding constant of the Markov-Cayley trees.
