Speech Title: Gradient Estimates for Weak Solutions of Elliptic PDE's
Abstract: Let us consider an elliptic equation of second order in variational form in a bounded domain of the Euclidean n dimensional space. The right hand side is a function satisfying suitable assumptions. The problem of gradient estimates for elliptic equations is very important both from theoretical and applied point of view. In this talk we exploit what is the heart of the technique to show gradient estimates allowing the function f to belong to very general function spaces. Our technique is very flexible and it is allowed to show existence, uniqueness and well posedness of the Dirichlet problem in several classes.
