Speaker: Giuseppe Mingione, University of Parma, Italy.
Title: Gradient estimates from uniformly to non-uniformly elliptic problems, Part 1
Abstract: I will give an overview of pointwise gradient estimates for solutions to nonlinear elliptic problems. I will initially recall some results known for uniformly elliptic problems then turning to non-uniformly elliptic ones.
10 pm Beijing Time (GMT+8):
Speaker: Sun-Sig Byun, Seoul National University, Korea.
Title: Global regularity estimates for nonlinear elliptic equations with nonstandard growth, Part 1
Abstract: A general class of nonlinear elliptic equations with nonstandard growth in nonsmooth domains is considered for the study of global gradient estimates of solutions.

Title: Potential theory and doubly nonlinear PDEs: estimates, existence, and removable sets, Part 1
Abstract: Recent advances in pointwise potential bounds and integral weighted estimates are discussed for a class of quasilinear elliptic equations with measure or distributional data. The connection of those estimates to Sobolev capacities and trace inequalities is presented. Applications include sharp existence criteria and characterizations of removable singular sets for doubly nonlinear equations of the form $-\Delta_p u= u^q +\sigma$, or $-\Delta_p u= |\nabla u|^q +\sigma$. Here $q>0$ could be arbitrarily large, $\Delta_p$ is the $p$-Laplacian ($p>1$), and $\sigma$ is a measure or sometimes a general signed distribution.
