Oscillation Criteria for Third-order Nonlinear Neutral Differential Equations with Distributed Deviating Arguments

The aim of this paper is to investigate the oscillation and asymptotic behavior of a class of third- order nonlinear neutral differential equations with distributed deviating arguments. By means of Riccati transformation technique and some inequalities, we establish several sufficient conditions which ensure that every solution of the studied equation is either oscillatory or converges to zero. Two examples are provided to illustrate the main results.
