Asymptotic properties of trinomial delay differential equations

Jozef Džurina, Renáta Kotorová (2008)

Archivum Mathematicum

Similarity:

The aim of this paper is to study asymptotic properties of the solutions of the third order delay differential equation 1 r ( t ) y ' ( t ) ' ' - p ( t ) y ' ( t ) + g ( t ) y ( τ ( t ) ) = 0 . * Using suitable comparison theorem we study properties of Eq. () with help of the oscillation of the second order differential equation.

This paper establishes oscillation theorems for a class of functional parabolic equations which arises from logistic population models with delays and diffusion.

Oscillation of a forced higher order equation

Witold A. J. Kosmala (1994)

Annales Polonici Mathematici

Similarity:

We state and prove two oscillation results which deal with bounded solutions of a forced higher order differential equation. One proof involves the use of a nonlinear functional.
