Periodic homogenisation of certain fully nonlinear partial differential equations. (English) Zbl 0796.35011
Summary: We demonstrate how a fairly simple “perturbed test function” method establishes periodic homogenisation for certain Hamilton-Jacobi and fully nonlinear elliptic partial differential equations. The idea, following Lions, Papanicolaou and Varadhan, is to introduce (possibly nonsmooth) correctors, and to modify appropriately the theory of viscosity solutions, so as to eliminate the effects of high-frequency oscillations in the coefficients.
