Abstract
We consider the family of all the Cellular Automata (CA) sharing the same local rule but have different memory. This family contains also all the CA with memory m ≤ 0 (one-sided CA) which can act both on A ℤ and on A ℕ. We study several set theoretical and topological properties for these classes. In particular we investigate if the properties of a given CA are preserved when we consider the CA obtained by changing the memory of the original one (shifting operation). Furthermore we focus our attention to the one-sided CA acting on A ℤ starting from the one-sided CA acting on A ℕ and having the same local rule (lifting operation). As a particular consequence of these investigations, we prove that the long-standing conjecture [Surjectivity \(\Rightarrow\) Density of the Periodic Orbits (DPO)] is equivalent to the conjecture [Topological Mixing \(\Rightarrow\) DPO].
