Abstract:
In this talk I will present some recent results obtained with Vladimir Maz`ya concerning functional dissipativity of some partial differential operators. This is a new concept of dissipativity which extends the notion of $L^p$-dissipativity. It turns out that the class of operators whose principal part is strictly $L^p$-dissipative coincides with the class of the so-called $p$-elliptic operators, which has recently been considered by several authors. I will focus in particular on systems in which different notions of ellipticity arise.
