Directional dynamics of ${\mathbb{Z}}_{+}\times \mathbb{Z}$-actions generated by 1D-CA and the shift map

Hasan Akın, Chunlin Liu

In this short paper, we compute the directional sequence entropy for of ${\mathbb{Z}}_{+}\times \mathbb{Z}$-actions generated by cellular automata and the shift map. Meanwhile, we stud…
