The ordering of critical periodic points in coordinate space by symbolic dynamics

Abstract In this paper, we study the symbolic dynamics equipped with the DGP product “∗” and the shift operator ϕ conjugate to the unimodal mapping f μ : I ↦ I over the interval I =[−1,1]. We prove two theorems, and give an explicit formula for the rule of ordering the points on the n -tupling periodic trajectory {ϕ k (σ ∗n (p+1))} in coordinate space with arbitrarily large p and n .
