摘要內容：
When the partial differential equations have oscillating data, the solution may oscillate around a limit function with some error. Then we may ask the effective equation (or Homogenized equation) satisfied by this limit function. In this talk we are going to introduce a viscosity method in homogenizations.
First, we will discuss why we need non-variational method in homogenization instead of the standard average of oscillating data. And then as an example, we will discuss the obstacle problem in a perforated domain.
