Non-transversal intersection of free and fixed boundary for fully nonlinear elliptic operators in two dimensions
Emanuel Indrei, Andreas Minne
In the study of classical obstacle problems, it is well known that in many configurations the free boundary intersects the fixed boundary tangentially. The arguments involved in pr…
