Characterization of shadowing for linear autonomous delay differential equations
Mihály Pituk, John Ioannis Stavroulakis (2025)
Czechoslovak Mathematical Journal
A well-known shadowing theorem for ordinary differential equations is generalized to delay differential equations. It is shown that a linear autonomous delay differential equation is shadowable if and only if its characteristic equation has no root on the imaginary axis. The proof is based on the decomposition theory of linear delay differential equations.

Classifications and existence of nonoscillatory solutions of second order nonlinear neutral differential equations
Wantong Li (1997)
Annales Polonici Mathematici
A class of neutral nonlinear differential equations is studied. Various classifications of their eventually positive solutions are given. Necessary and/or sufficient conditions are then derived for the existence of these eventually positive solutions. The derivations are based on two fixed point theorems as well as the method of successive approximations.

Comparison theorems for the third order trinomial differential equations with delay argument
Jozef Džurina, Renáta Kotorová (2009)
Czechoslovak Mathematical Journal
In this paper we study asymptotic properties of the third order trinomial delay differential equation by transforming this equation to the binomial canonical equation. The results obtained essentially improve known results in the literature. On the other hand, the set of comparison principles obtained permits to extend immediately asymptotic criteria from ordinary to delay equations.
