Abstract

In this paper we study qualitative geometric properties of optimal configurations to a variational problem with free boundary, under suitable assumptions on a fixed boundary. More specifically, we study the problem of minimizing the flow of heat given by , where is a fixed domain and is the potential of a domain , with a prescribed volume on . Our main goal is to establish uniqueness and symmetry results when has a given geometric property. Full regularity of the free boundary is obtained under these symmetry conditions imposed on the fixed boundary.
