Resumen de On the image set and reversibility of shift morphisms over discrete alphabets

Jorge Campos, Neptalí Romero, Ramón Vivas

• We provide sufficient conditions in order to show that the image set of a continuous and shift-commuting map defined on a shift space over an arbitrary discrete alphabet is also a shift space. Additionally, if such a map is injective, then its inverse is also continuous and shift-commuting.
