Pankov, A. A. Averaging of nonlinear elliptic operators with nonuniformly oscillating coefficients. (Russian) Zbl 0825.35010 Mat. Fiz. Nelineĭn. Mekh. 14(48), 83-86 (1990). The procedure of averaging is justified for nonlinear operators whose coefficients contain both the rapid and slow variables. For simplicity, only second order operators are discussed.
