## Homogenization of fully nonlinear, uniformly elliptic and parabolic partial differential equations in stationary ergodic media.(English)Zbl 1063.35025

The authors study the homogenization of fully nonlinear elliptic or parabolic equation in stationary ergodic media. They prove in particular that if the nonlinearity $$F$$ is stationary ergodic in the fast variable the limit problem does not contain any probabilistic variable. The methods used in the periodic or almost periodic case does not work in this case and the method used here is new and based on the investigation of the obstacle problem relative to a fully nonlinear operator.
