Multiple Techniques for Studying Asymptotic Properties of a Class of Differential Equations with Variable Coefficients
Keyword(s):
This manuscript is concerned with the oscillatory properties of 4th-order differential equations with variable coefficients. The main aim of this paper is the combination of the following three techniques used: the comparison method, Riccati technique and integral averaging technique. Two examples are given for applying the criteria.
