In this paper, some sufficient conditions are obtained by discussing the oscillatory behavior of solutions for a class of even-order nonlinear functional differential equations, and our results generalize and improve some known results.

This paper studied the asymptotic behavior of a class of nonlinear functional differential equations by using the Bellman-Bihari inequality. We obtain results which extend and complement those in references. The results indicate that all non-oscillatory continuable solutions of equation are asymptotic to at+b as under some sufficient conditions, where a,b are real constants. An example is provided to illustrate the application of the results.
