Improving sharp Hardy-Sobolev inequalities by optimal remainder norms

by Adele Ferone | Seconda Università di Napoli
Time: 11:10  (Thursday, Jul. 08, 2010)
Location: BA6183, Bahen Center, 40 St George St
Abstract:
In this talk, I will discuss the main ideas and steps contained in the following joint papers with A. Cianchi:
  • Best Remainder Norms in Sobolev-Hardy inequalities, Indiana Univ. Math. J. 58 (2009), no. 3, 1051-1096
  • Improving sharp Hardy-Sobolev inequalities by optimal remainder gradient norms, submitted.
We are concerned with the Sobolev inequality in $W^{0,p}(\Omega)$ with optimal target space and sharp constant. Admissible remainder terms depending on the function or on its gradient are characterized. As a consequence, the strongest possible remainder norms are exhibited. Related Hardy inequalities with remainders are also derived.
