Positive solutions of second-order delay differential equations with a damping term
نویسندگان
چکیده
In the paper, the existence of positive solutions is studied for the second-order delay differential equation with a damping term ẍ(t)+ a(t)ẋ(t)+ b(t)x(h(t)) = 0 using a comparison with the integro-differential equation ẏ(t)+ ∫ t t0 e ∫ t s a(ξ)dξb(s)y(h(s))ds = 0. Explicit non-oscillation criteria and comparison type results are derived. © 2010 Elsevier Ltd. All rights reserved.

Positive Solutions of a Boundary-value Problem for a Differential Equation with Damping and Actively Bounded Delayed Forcing Term
Sufficient conditions are given for the existence of positive solutions of a boundary-value problem concerning a second-order delay differential equation with damping and forcing term whose the delayed part is an actively bounded function, a meaning which is introduced in this paper. The Krasnoselskii fixed point theorem on cones in Banach spaces is used.
متن کاملPERIODIC SOLUTIONS FOR n-TH ORDER DELAY DIFFERENTIAL EQUATIONS WITH DAMPING TERMS
where n is a positive integer, s ≤ n − 1 a positive integer, bi(i = 1, · · · , s) are constants and k > 1 is an integer, f ∈ C(R,R) for ∀x ∈ R, p ∈ C(R,R) with p(t+ T ) = p(t). In recent years, some researchers used the coincidence degree theory of Mawhin to study the existence of periodic solutions of first, second or third order differential equations [5, 6], [9][15]–[19], [22, 23], [25, 26]....
متن کاملOn the Dynamic of a Nonautonomous
Nonlinear difference equations of higher order are important in applications; such equations appear naturally as discrete analogues of differential and delay differential equations which model various diverse phenomena in biology, ecology, economics, physics and engineering. The study of dynamical properties of such equations is of great importance in many areas. The autonomous difference equat...
متن کاملAnalytic Solution of Fuzzy Second Order Differential Equations under H-Derivation
In this paper, the solution of linear second order equations with fuzzy initialvalues are investigated. The analytic general solutions of them using a rstsolution is founded. The parametric form of fuzzy numbers to solve the secondorder equations is applied. The solutions are searched in four cases. Finallythe example is got to illustrate more and the solutions are shown in gures forfour cases.
متن کاملShifted Chebyshev Approach for the Solution of Delay Fredholm and Volterra Integro-Differential Equations via Perturbed Galerkin Method
The main idea proposed in this paper is the perturbed shifted Chebyshev Galerkin method for the solutions of delay Fredholm and Volterra integrodifferential equations. The application of the proposed method is also extended to the solutions of integro-differential difference equations. The method is validated using some selected problems from the literature. In all the problems that are considered...
