We consider functionals given by the sum of the perimeter and the double integral of some kernel g : R-N x R-N -> R+, multiplied by a "mass parameter" epsilon. We show that, whenever g is admissible, radial and decreasing, the unique minimizer of this functional among sets of given volume is the ball as soon as epsilon << 1.

Abstract

We consider functionals given by the sum of the perimeter and the double integral of some kernel g : R-N x R-N -> R+, multiplied by a "mass parameter" epsilon. We show that, whenever g is admissible, radial and decreasing, the unique minimizer of this functional among sets of given volume is the ball as soon as epsilon << 1.
