Constrained and unconstrained rearrangement minimization problems related to the p-Laplace operator

Abstract

In this paper we consider an unconstrained and a constrained minimization problem related to the boundary value problem
??pu = f in D, u = 0 on ?D.
In the unconstrained problem we minimize an energy functional relative to a rearrangement class, and prove existence of a unique solution. We also consider the case when D is a planar disk and show that the minimizer is radial and increasing. In the constrained problem we minimize the energy functional relative to the intersection of a rearrangement class with an affine subspace of codimension one in an appropriate function space. We briefly discuss our motivation for studying the constrained minimization problem.
