Oscillatory solutions of nonlinear fourth order differential equations with a middle term
We study the oscillation of a fourth order nonlinear differential equation with a middle term. Using a certain energy function, we describe the properties of oscillatory solutions. The paper extends oscillation criteria stated for equations with the operator $x^{(4)} + x''$ and completes t...
