Boundedness of solutions for a class of Liénard equations with a deviating argument
Consider the Liénard equation with a deviating argument x (t)+ f (x(t))x (t)+ g1(x(t))+ g2(x(t − τ(t))) = e(t), where f, g1 and g2 are continuous functions on R = (−∞,+∞), τ (t) ≥ 0 is a bounded continuous function on R, and e(t) is a bounded continuous function on R = [0,+∞). We obtain some new sufficient conditions for all solutions and their derivatives to be bounded, which substantially ext...
متن کاملExistence and uniqueness of periodic solutions for a kind of Liénard equation with a deviating argument
In this work, we use the coincidence degree theory to establish new results on the existence and uniqueness of T -periodic solutions for a kind of Liénard equation with a deviating argument of the form x (t)+ f (x(t))x (t)+ g(t, x(t − τ(t))) = p(t). c © 2007 Elsevier Ltd. All rights reserved.
متن کاملPositive 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 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.
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.
