A typical operator is $H^{a_1,a_2}(Q,x) = a_1(x) \\lambda_{\\min}(Q) + a_2(x)\\lambda_{\\max}(Q)$. Linearization of the operator leads to a non-divergence form homogenization problem, which can be solved by averaging against the invariant measure. We estimate the error obtained by linearization based on semi-concavity estimates on the nonlinear operator. These estimates show that away from high curvature regions, the linearization can be accurate.
