In the last year,in collaboration with Ariela Briani and Hitoshi Ishii we have extended the classical result on thin domains that was started by Hale and Raugel to viscosity solutions setting.  Our approach differs from those that have characterize all the subsequent works in the sense that we use an "à la Evans" technique often called the test function approach. It allows to treat fully nonlinear equations, oblique boundary conditions, etc...
