The main purpose of this manuscript is to show asymptotic properties of a class of differential equations with variable coefficients r ν w ν β + i = 1 j q i ν y κ g i ν = 0 , where ν ν 0 and w ν : = y ν + p ν y σ ν . By using integral averaging technique, we get conditions to ensure oscillation of solutions of this equation. The obtained results improve and generalize the earlier ones; finally an example is given to illustrate the criteria. View Full-Text
