A geometrical approach to the sharp Hardy inequality in Sobolev-Slobodecki\uı spaces
Francesca Bianchi, Giorgio Stefani, Anna Chiara Zagati
We give a partial negative answer to a question left open in a previous work by Brasco and the first and third-named authors concerning the sharp constant in the fractional Hardy i…
On the sharp Hardy inequality in Sobolev-Slobodecki\uı spaces
Francesca Bianchi, Lorenzo Brasco, Anna Chiara Zagati
We study the sharp constant in the Hardy inequality for fractional Sobolev spaces defined on open subsets of the Euclidean space. We first list some properties of such a constant,…
A note on the supersolution method for Hardy's inequality
Francesca Bianchi, Lorenzo Brasco, Firoj Sk +1
We prove a characterization of Hardy's inequality in Sobolev-Slobodecki\uı spaces in terms of positive local weak supersolutions of the relevant Euler-Lagrange equation. This exten…
