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.
متن کاملAlmost periodic solutions for a class of fourth-order nonlinear differential equations with a deviating argument
This work is concernedwith a class of fourth order semilinear ordinary differential equation with pseudo almost periodic environment and multiple delays. Specifically, we establish the existence and uniqueness of the pseudo almost periodic solutions. Furthermore, we discuss the global stability of the considered equation.
متن کاملAnti-Periodic Solutions for a Class of Third-Order Nonlinear Differential Equations with a Deviating Argument
In this paper, we study a class of third-order nonlinear differential equations with a deviating argument and establish some sufficient conditions for the existence and exponential stability of anti-periodic solutions of the equation. These conditions are new and complement to previously known results.
