Abstract:
We discuss the relations between two types of fractional Laplacians
– “Dirichlet” and “Navier” ones – in bounded domains in $\mathbb R^n$.
Then we prove the coincidence of the Sobolev and Hardy constants relative
to these operators of any real order $m\in(0,\frac{n}{2})$.
This talk is based on joint papers with Roberta Musina, see [1], [2], [3].
