Abstract.  In this paper, we consider the completions of locally convex spaces, the completions of metric linear spaces and present several new structural results concerning the (Stepanov) ρ-almost periodic functions with values in locally convex spaces. We formulate and prove the Bochner criterion for the (Stepanov) almost periodic functions with values in non-complete locally convex spaces.
Keywords: ρ-almost periodic functions, Stepanov ρ-almost periodic functions, locally convex spaces, metric linear spaces, completions.
