Optimal Rellich-Sobolev constants and their extremals

Analysis of PDEs 2014-01-28 v3

Abstract

We prove that extremals for second order Rellich-Sobolev inequalities have constant sign. Then we show that the optimal constants in Rellich-Sobolev inequalities on a bounded domain {\Omega} and under Navier boundary conditions do not depend on {\Omega}
