We present and discuss some open problems related to the determination of a set K from its covariogram, i.e. the function which provides the volumes of the intersections of K with all its possible translates.
Filippo Gazzola
We discuss the geometric approach developed in [8] for the study of overdetermined boundary value problems for general elliptic operators.We show that this approach does not apply when nonconstant sources are involved.
Ermanno Lanconelli
Let L be a real sub-Laplacian on a stratified Lie group G. In this note we present some results on the Dirichlet problem for L with L^p-boundary data, on domains which are contractible with respect to the natural dilations of G. One of the main difficulti... see more

The main purpose of this lecture is to present some basic notions on variational and variational-hemivariational inequalities as well as two recent existence results in the elliptic case. A wide bibliography is also provided.

We present existence results for a class of non-uniformly elliptic problems.[omissis]
Abdelhafid Mokrane, François Murat
In this paper, we present two results that we recently proved in [18] and [19]: on the first hand, the Lewy-Stampacchia’s inequality for the bilateral obstacle problem with a fairly general Leray-Lions operator; on the second hand, again the Lewy-Stampacc... see more

Equations of mixed elliptic-hyperbolic type with a homogeneous Dirichlet condition imposed on the entire boundary will be discussed. Such closed problems are typically overdetermined in spaces of classical solutions in contrast to the well-posedness for c... see more

We discuss the problem of the steady two-dimensional flow past fixed disturbances in an open channel of finite depth. We consider different types of obstacles, like submerged or surface-piercing bodies, and localized perturbations of a horizontal bottom; ... see more

We deal with the Dirichlet problem in a bounded smooth domain.[omissis]
Maria Michaela Porzio
The results presented here are obtained with Lucio Boccardo and regards some nonlinear elliptic problems.[omissis]
