Positive almost periodic solutions for a class of nonlinear Duffing equations with a deviating argument
In this paper, we study a class of nonlinear Duffing equations with a deviating argument and establish some sufficient conditions for the existence of positive almost periodic solutions of the equation. These conditions are new and complement to previously known results.
