Giovanni Alessandrini

Inverse boundary value problems are those in which one wants to determine physical parameters associated to the interior of a certain body, or region, from measurements taken from the exterior.

We compare the concentration of the solution of elliptic variational inequalities by the concentration of the solution of suitable symmetrized problems.

Orazio Arena, Paolo Manselli

In the context of second order linear uniformly elliptic equations with measurable coefficients, a result of Freidlin [9], which deals with homogenization type properties for elliptic equations with smooth periodic coefficients, is extended to generalized... see more

Lucio Boccardo, G. Rita Cirmi

In this note we prove some existence and regularity results for unilateral problems with degenerate coercivity.

We describe recent results on the regularity for the Stefan problem obtained in a joint work with I. Athanasopoulos and L. Caffarelli.
