By using a fixed point theorem, weighted pseudo almost periodic functions and differential inequality techniques, we establish new criteria for existence,uniqueness and globally exponential stability of weighted pseudo almost periodic solutions. An example with its numerical simulation is given to show the applicability of the proposed results. The results obtained is new and complements that found in the literature. © 2017 NSP.eninfo:eu-repo/semantics/closedAccessDichotomyDuffing EquationFixed PointVariable Time LagWeighted Pseudo Almost Periodic SolutionArticle116N/AQ316091614
