By using averaging techniques, some oscillation criteria for quasilinear elliptic differential equations of second order are obtained. These results extend and generalize the criteria for linear differential equations due to Kamenev, Philos and Wong. 2000 Mathematics Subject Classification: 35B05, 35J60, 34C10.
