Comparison theorems for noncanonical third order nonlinear differential equations

Ivan Mojsej, Ján Ohriska (2007)

Open Mathematics

Similarity:

The aim of our paper is to study oscillatory and asymptotic properties of solutions of nonlinear differential equations of the third order with quasiderivatives. We prove comparison theorems on property A between linear and nonlinear equations. Some integral criteria ensuring property A for nonlinear equations are also given. Our assumptions on the nonlinearity of f are restricted to its behavior only in a neighborhood of zero and a neighborhood of infinity.

We study solutions tending to nonzero constants for the third order differential equation with the damping term ( a 1 ( t ) ( a 2 ( t ) x ' ( t ) ) ' ) ' + q ( t ) x ' ( t ) + r ( t ) f ( x ( ϕ ( t ) ) ) = 0 in the case when the corresponding second order differential equation is oscillatory.
