Oscillation of high order linear functional differential equation with impulses

open access: yesElectronic Journal of Differential Equations, 2005
We study the solutions to high-order linear functional differential equations with impulses. We improve previous results in the oscillation theory for ordinary differential equations and obtain new criteria on the oscillation of solutions.

Impulsive functional‐differential equations with nonlocalconditions [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
The existence, uniqueness, and continuous dependence of a mild solution of an impulsive functional‐differential evolution nonlocal Cauchy problem in general Banach spaces are studied. Methods of fixed point theorems, of a C0 semigroup of operators and the Banach contraction theorem are applied.

Oscillations of Higher Order Functional Differential Equations with Impulses [PDF]

open access: yesgmj, 2006
Abstract A kind of higher order sub-and super-linear FDE with impulses is studied in this paper. Several criteria on the oscillations of solutions are given. In particular, in the case where the coefficients of equations are positive and continuous functions, we find some suitable impulse functions such that all solutions of the equation

MultiPoint BVPs for Second‐Order Functional Differential Equations with Impulses [PDF]

open access: yesMathematical Problems in Engineering, 2009
This paper is concerned about the existence of extreme solutions of multipoint boundary value problem for a class of second‐order impulsive functional differential equations. We introduce a new concept of lower and upper solutions. Then, by using the method of upper and lower solutions introduced and monotone iterative technique, we obtain the ...
