Regularizing effect of the lower order terms in some elliptic problems: old and new
Summary: This paper is divided in two parts: the first one is a survey about recent results on the regularizing effect of lower order terms on solutions of nonlinear Dirichlet problems; in the second part we prove two existence theorems (related to the results of the first part) concerning elliptic systems.
