Nonlinear Measure Data Problems
Milan Journal of Mathematics, 2011This paper is a survey of some regularity results for solutions to measure data problems, i.~e. solutions of the equation \(-\text{div}\,a(x,Du) = \mu\), where \(\mu\) is a measure on a bounded open set \(\Omega \subset \mathbb{R}^{n}\). After two introductory sections, the basic regularity results are given. These results are new in the sublinear case,

Nonlinear subelliptic Schrödinger type problems
Nonlinear Analysis: Theory, Methods & Applications, 1997Let \(X_i =\sum_{j=1}^n a_{ij}D_{x_j}, i=1,...,m, a_{ij} \in C^{\infty}(\mathbb{R}^N)\), be vector fields on \(\mathbb{R}^N, N\geq 2\) satisfying the Hörmander condition, \(X_i^*=- \sum_{j=i}^N D_{x_j}(a_{ij} \cdot), Xu=(X_1u,...,X_mu)\). A distance relative to the vector fields \(X_i\) is defined as \[ d(x,y)= \sup\{\Phi(x)- \Phi(y): \Phi \in C_0 ...
