Abstract

We investigate computable subshifts and the connection with effective symbolic dynamics. It is shown that a decidable View the MathML source class P is a subshift if and only if there is a computable function F mapping View the MathML source to View the MathML source such that P is the set of itineraries of elements of View the MathML source. A View the MathML source subshift is constructed which has no computable element. We also consider the symbolic dynamics of maps on the unit interval.

Keywords: Computability; symbolic dynamics; View the MathML source Classes
