In this article, we establish some new criteria for the oscillation of fourth order nonlinear delay differential equations of the form x(t) + p(t)x(t) + q(t)f(x(g(t))) = 0 provided that the second order equation z(t) + p(t)z(t) = 0 is nonoscillatiory or oscillatory. This equation with g(t) = t is considered in [8] and some oscillation criteria for this equation via certain energy functions are ...

The authors obtain necessary and sufficient conditions for the existence of oscillatory solutions with a specified asymptotic behavior of solutions to a nonlinear neutral differential equation with distributed delay of third order. We give new theorems which ensure that every solution to be either oscillatory or converges to zero asymptotically. Examples dwelling upon the importance of applicab...
