Abstract
The obstacle problem is more than half a century old, but remains a relevant topic in mathematics due to the many variants and applications that occur in, for instance, physics, finance and potential theory. In the seminar we will briefly go over the classical obstacle problem and some variations, and present some recent results in the fully non-linear case. The main focus will be optimal regularity of solutions.
