Abstract

The purpose of this work is to study remotely almost periodic functions defined on the semi-axis + := [ 0 , + ) (respectively, on the real axis := ( - , + ) ) with values in the Banach space 𝔅 . We establish a relation between remotely almost periodic movements in the shift dynamical system ( C ( 𝕋 , 𝔅 ) , 𝕋 , σ ) ( 𝕋 = + or ) in the space of continuous functions C ( 𝕋 , 𝔅 ) and remotely almost periodic functions. Using this connection, we prove some important analytical and topological properties of remotely almost periodic functions.
