Oscillation of a forced higher order equation

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.

On oscillation criteria for third order nonlinear delay differential equations

Ravi P. Agarwal, Mustafa F. Aktas, Aydın Tiryaki (2009)

Archivum Mathematicum

Similarity:

In this paper we are concerned with the oscillation of third order nonlinear delay differential equations of the form r 2 t r 1 t x ' ' ' + p t x ' + q t f x g t = 0 . We establish some new sufficient conditions which insure that every solution of this equation either oscillates or converges to zero.
