On a Class of Functional Differential Equations Having Slowly Varying Solutions
Functional differential equations with deviating arguments are studied for the first time in the framework of Karamata regularly varying functions. A sharp condition is established for the existence of slowly varying solutions for a class of second order linear equations of the form x′′ = q(t)x(g(t)), both in the retarded and in the advanced case.
متن کاملOscillatory Properties of Solutions of Impulsive Differential Equations with Several Retarded Arguments
The impulsive differential equation x′(t) + m ∑ i=1 pi(t)x(t− τi) = 0, t 6= ξk, ∆x(ξk) = bkx(ξk) with several retarded arguments is considered, where pi(t) ≥ 0, 1 + bk > 0 for i = 1, . . . , m, t ≥ 0, k ∈ N. Sufficient conditions for the oscillation of all solutions of this equation are found. §
متن کاملRegularly Varying Solutions of Perturbed Euler Differential Equations and Related Functional Differential Equations
An asymptotic analysis in the framework of Karamata regularly varying functions is performed for the solutions of second order linear differential and functional differential equations in the critical case i.e., when condition (1.5) as given below, holds.
متن کاملHeteroclinic Orbits for Retarded Functional Differential Equations*
Suppose r is a heteroclinic orbit of a Ck functional differential equation i(t) =f(x,) with a-limit set a(T) and o-limit set w(T) being either hyperbolic equilibrium points or periodic orbits. Necessary and sufficient conditions are given for the existence of an 7 close to f in Ck with the property that i(t) = 3(x,) has a heteroclinic orbit p close to f. The orbits p are obtained from the zeros...
متن کاملErgodic Type Solutions of Differential Equations with Piecewise Constant Arguments
We summarize the conditions discovered for the existence of new ergodic type solutions (asymptotically almost periodic, pseudo almost periodic, . . .) of differential equations with piecewise constant arguments. Their existence is characterized by introducing a new tool, the ergodic sequences. 2000 Mathematics Subject Classification. 39-02, 34K14, 34D09.
