Fourth-Order Differential Equation with Deviating Argument
We consider the fourth-order differential equation with middle-term and deviating argument x(4)(t)+q(t)x(2)(t)+r(t)f(x(φ(t)))=0, in case when the corresponding second-order equation h″+q(t)h=0 is oscillatory. Necessary and sufficient conditions for the existence of bounded and unbounded asymptotical...
