Optimization problem for extremals of the trace inequality in domains with holes

Analysis of PDEs 2013-11-15 v1

Abstract

We study the Sobolev trace constant for functions defined in a bounded domain \O\O that vanish in the subset A.A. We find a formula for the first variation of the Sobolev trace with respect to hole. As a consequence of this formula, we prove that when \O\O is a centered ball, the symmetric hole is critical when we consider deformation that preserve volume but is not optimal for some case.
