Nonlinear potential theory and PDEs
The author considers a class of equations similar to \((*)\) \(-\text{div}(|\nabla u|^{p- 2} \nabla u)= \mu\), where \(\mu\) is a nonnegative Radon measure and \(1< p< \infty\). The main topics discussed are the relation between \(p\)-superharmonic functions and distributional solutions of \((*)\), and the Wiener criterion for the regularity of boundary points for such equations.
