Dr. Gloria Paoli “The Talenti comparison result in a quantitative form”

We obtain a quantitative version of the classical comparison
result of Talenti for elliptic problems with Dirichlet boundary
conditions. The key role is played by quantitative versions of the
Pölya-Szegő inequality and of the Hardy-Littlewood inequality.

This is a joint work, in collaboration with Vincenzo Amato, Rosa Barbato

and Alba Lia Masiello.
