|TITLE||Potential estimates for nonlinear elliptic measure data problems with obstacle|
In this talk, we study the recent progress in the regularity theory for nonlinear elliptic measure data problems with obstacles and some difficulties arising from obtaining the gradient Riesz potential estimates for such problems. The interaction between the right-hand side and the obstacles makes it hard to get optimal linearized comparison estimates and potential estimates. We will see some methods to overcome such difficulties in this talk.
