Homogenization of an obstacle problem with highly oscillating coefficients and obstacles
Sunghoon Kim, Ki-Ahm Lee, Se-Chan Lee +1
We develop the viscosity method for the homogenization of an obstacle problem with highly oscillating obstacles. The associated operator, in non-divergence form, is linear and elli…
