Maximum principle, mean value operators and quasi boundedness in non-euclidean settings
This work deals with some classes of linear second order partial differential operators with non-negative characteristic form and underlying non- Euclidean structures. These structures are determined by families of locally Lipschitz-continuous vector fields in RN, generating metric spaces of …

REGULARITY RESULTS FOR QUASILINEAR EQUATIONS OF ANISOTROPIC TYPE AND OF MIXED LOCAL-NONLOCAL TYPE
La seguente tesi ha come obiettivo quello di studiare la regolarita' interna e al bordo per soluzioni di equazioni ellittiche quasilineari. In particolare, si studia la regolarita' del secondo ordine delle soluzioni di equazioni nonlineari in cui operatore e' di tipo locale ed anisotropo. Inoltre, …

Intrinsic Lipschitz graphs in Heisenberg groups and non linear sub-elliptic PDEs
… In particular we provide a regular approximation result and a Poincarè type inequality for this class of functions. Moreover we study the obstacle problem in the Heisenberg group and we prove a geometric Poincarè inequality for a class of semilinear equations in the Engel group.
