On the Oscillatory Behavior of a Class of Fourth-Order Nonlinear Differential Equation.

In this work, we study the oscillatory behavior of a class of fourth-order differential equations. New oscillation criteria were obtained by employing a refinement of the Riccati transformations. The new theorems complement and improve a number of results reported in the literature. An example is provided to illustrate the main results. [ABSTRACT FROM AUTHOR]
