Asymptotic character of non-oscillatory solutions to functional differential system
Electronic Journal of Qualitative Theory of Differential Equations, 2015 In this paper the behaviour of solutions to systems of three functional differential equations is investigated. We are interested in the acquirement of conditions which ensure that certain of four possible non-oscillatory types holds.

Advanced Engineering Materials, EarlyView.Si‐doped AlCoCrFeNi high‐entropy alloys are synthesized by mechanical alloying to reveal the effect of Si content and milling time on phase evolution, microstructural refinement, and tribological behavior. A transition from FCC to BCC structure, significant grain refinement, and enhanced hardness and wear resistance are achieved, with the 4 at% Si ...

Advances in Mathematical Physics, 2017 We consider a kind of second-order neutral functional differential equation. On the basis of Mawhin’s coincidence degree, the existence and uniqueness of periodic solutions are proved. It is indicated that the result is related to the deviating arguments.

Periodic solutions of convex neutral functional differential equations
Tohoku Mathematical Journal, 2000 In this paper, the authors study the existence of periodic solutions to neutral differential equations. It is proved that for convex neutral functional-differential equations of \(D\)-operator type with finite (or infinite) delay and hyperneutral functional-differential equations with finite delay the problem of the existence of periodic solutions is ...

Periodic solutions to a kind of neutral functional differential equation in the critical case [PDF]
, 2004 In this paper, we consider a kind of neutral functional differential equation as follows: x(t)−cx(t−τ)′=gt,xt−μ(t)+e(t) in the critical case |c|=1. By employing the topological degree theory and some analysis techniques, we obtain some new results on the
